My biology teacher once told me: "The nucleus of a cell is like your local library, it contains and houses all the books and information you will ever need. The DNA is like the reference section of the library, you are not allowed to remove any of the reference books from the building, as the librarians don't want these irreplaceable books lost or damaged. However you are allowed to "photocopy" the pages to use the information, as whats the point in having information you can not use. Once you have "photocopied" the information you need, you can then use this information for what ever purpose." The "photocopies of the reference book" represent the mRNA transcripted from the DNA. The mRNA then travels outside the nucleus to be translated by a ribosome to create the protein the mRNA encodes for. This is done by connecting amino acids together in chains. The protein created is then exported out the cell to be used for its function. This is a very simplified version of the entire transcription and translation process. I am happy to answer any questions I am capable of, and give a slightly more in depth overview if asked for. But what my biology teacher told me, helped me understand the overall process, and i think is a very clear and clever analogy. Great vid by the way.
Hi, thank you for sharing such relevant information, I just have a question but I may be a little too late to ask since your comment is 4 years old, but is there any difference between RNA and genes? Are they the same, and if not what's their main difference
One of the best explanations I've encountered. You guys are undoubtedly aware that the brain best recalls the first and last, and in that way you summerise it all in a clear language at the end. Thank you!
Just showed some Stated Clearly videos to my 6 year old grandchildren and they were fascinated! Well done on making those difficult subjects understandable for kids!
/continued/ The ribosomes recognizes certain letters as 'start reading now' signals, using basic chemistry. This is a simplification but it's broadly valid - some bits of the ribosome chemically bind to some specific bits of nucleic acid it reads. It then accepts amino acids (the building blocks of proteins) that are connected to 3 special letters of nucleic acid into it. If the 3 letters bind the nucleic acid, the amino acid is released and quickly binds to the growing protein.
/continued/ You can (and often have to) modify the genes when you insert them into the host you want to express them. You may have to add an on/off switch that works in the host; plants and animals often use different switches for that. Most proteins are made of discreet subunits, each with a specific function. You can even add individual subunits to another gene so a protein gains a new function; adding a 'tag' so you can see where it is for example.
Fantastically clear explanation, remit achieved, thank you. It amazes me that these sequences successfully instruct molecules to get to work. It almost seems that the DNA sequences and the protein-building molecules are capable of independent thought! I'm guessing that's not actually the case, but do you know the process by which they apparently understand what job they are meant to be doing?
The individual parts in the process are absolutely clueless about the big picture. It just happens to be that those parts which do better job are more likely to get passed on than those who do crappy job.
The molecules communicate with each other by touch. Each one has a characteristic shape, and fits together with certain other molecules like puzzle pieces. This 'touch and fit' also involves static cling: many molecules have numerous charged parts that attract opposite charge. Imagine running around blindfolded, wearing patches of velcro hooks and/or loops on various parts of your body, in a huge crowd of blindfolded people, all similarly attired with variously patterned velcro suits, and all in a big hurry. After many collisions, you would find someone that you stick to particularly well. This works fine in cells, where each molecule collides with other molecules about a billion times per second. The other ability that allows protein molecules to act 'intelligently' is that each can flip between two or three different functional shapes. This allows other molecules to flip them 'on' or 'off.'
This one is a little confusing at 0:23 as it shows the DNA split apart but then it makes it look as though A interlocks with C and T interlocks with G. As you know, A combines with T and C with G, so it would have been clearer to have the 4 nucleotides displayed in the same sequence that they’re in on top of the ladder, with the red and blue together on top and then the yellow and green on bottom.
This confused me for a long time until I remembered the DNA isn't the only thing that goes into the daughter cell when it divides; the cytoplasm (the juice inside the cell) goes into the 2 daughters as well. This contains the little machines that read the DNA (ribosomes) including the genes that encode them! Ribosomes work because each letter in DNA selectively binds one of the other letters. Amino acids (which make proteins) are bound to 3 letters that bind specifically to 3 other letters
/continued/ Each of the letters in DNA weakly chemically binds 1 of the other letters. The amino acids that build up proteins float around the cell connected to little RNA molecules (like DNA only single stranded) that have 3 special letters. If this RNA enters the ribosome and these letters chemically bond to the letters on the DNA (not to get too complicated but they actually bind a single stranded RNA, copied from the DNA by another machine) then it will add it's amino acid to the protein.
At the 1m10s mark, how was it determined where one gene ends and another begins? i.e. each gene length? According to Jennifer Doudna, the CRISPR/CAS9 protein requires a 20 nucleotide RNA sequence to uniquely define a section of DNA. Also I dug the part (3m35s mark) about how we can get bacteria to create our protein-chain (peptide hormone) insulin!
wow........cleared so many doubts and questions that was running in my head while reading GENETICS...thanx a tonne...brilliant...so nicely stated and animated,....thanx...! ! ! :) :) :)
What's with the "supposedly" on the gmo corn? Science is based on evidence, not belief. Whether people like it or not, the evidence shows that gmo corn is just as safe for human consumption as any other corn. Please do NOT make a science video then interject the science with your personal belief. Now, you could have said that corn monoculture is of scientific concern, because there is evidence that agricultural monoculture can lead to famine.
+carrie dollar ah, you noticed that, huh? This video was written before I had science advisors working with me. At the time there were concerns being raised by Bill Nye on the issue which was what inspired the wording. If we end up finding funding to make Stated Clearly a full time gig, this is one of the videos that will get reworked.
Imo, the use of the word "supposedly" is warranted here.. This is a relatively new technology so we are not 100% sure if it is entirely safe for us or not.. Only time will tell my fellow guinea pigs : )
As Patrick says, it's too early to be totally sure, despite what your hoped-for corporate sponsors at humanitarian organizations like Monsanto tell you. In the interest of intellectual integrity, you need to use AND KEEP the word 'supposedly' right where it is.
A little bit of thinking here.Genes aren't really the basic units of information in the world, but protons are. The number of protons determine the identity of an atom and atoms determine molecules. Molecules in turn make up the identity of DNA & RNA strands.Remove an electron or neutron from something; it doesn't affect it much. But remove a proton from it and everything crumbles down....
cortster12 the problem with america is that there is not a good school system, some teach creationism and others both and others evolution, it is so rediculous it gets me angry
emiel teamsup I have never heard of a school, other than private christian schools, that actually teach religion in school. none. The school system sucks, don't get me wrong, but it isn't that bad... at least, not in Washington State it isn't.
cortster12 lol, .... there even are universities/schools who expelled/banned students for starting an atheist group... (like a music group or game group)
0:25 all i needed most other sources talked about what a gene dose and what DNA is and chromosomes and all i wanted to know specifically what a gene is, thanks
Thank you for the information on DNA and genes. Its interesting to know that all living things are somewhat related by a basic 'code'. Keep making more video's, they are very informative. (;.
A lot of colleges (Berkley, Yale, Standford, MIT, etc) put their lecture series online. Bozeman biology and crash course biology are both good sets of videos on the topic if you want to learn more about it without books. I'm a terrible reader so love watching stuff like this when i feel like learning! Hope you did well in your finals :S That you passed them doesn't mean you have to stop learning though, so many resources are online to learn from if you want it :P
Great !!! Can you make videos on genetic modification and how genes and cloning are related. other topics are evolutionary biology, neurophysiology and similar new disciplines/
/continued 3/ I see why they left these details out! It's complicated and possibly confusing. I hope i explained it OK but if not, check videos on translation and transcription, they will explain it better! In short, RNA is not part of the DNA. A different little machine reads a 'start making RNA now' sequence on the DNA and makes a little 'messenger' RNA copy of the DNA, which is then read into protein. A gene is technically defined as a section of DNA that codes for 1 RNA (and thus 1 protein)
So those RNA copies that go from the nucleus to cytoplasm for rybosomes to make proteins from aminoacids, those are always segmented at exactly the gene boundaries? In other words, the "copy machine" works on a gene level?
/continued 3/ The way genes coooperate with other genes to make things like fins and wings and only work at specific times in development mean making a 'half fish' or a 'half bird' would be especially hard and not that useful compared to curing (specific forms of) cancer or blindness.
+Price Chinedum An allele is just a specific variation of a gene, so it's still accurate to just say that your genes determine your characteristics (though the new field of epigenetics is demonstrating that things are far, FAR more complicated than gene -> trait). The term allele has more use when comparing between versions of the same gene.
Wow thanks for the vey informative and fun videos. I was an average high school student, didn't do well in chemistry or so much as take a biology class but I always knew something was innate, or going on inside of us that influenced our behavior and physical traits e.g.homosexuality...I am a blue collarworker who likes to learn how stuff works in nature lol...looking forward to more simplified easy to grasp and hold onto info!
There are lots of things going on inside of us that affect us but its hard to see how homosexuality could be an inherritable genetic trait. If it were, surely the frequency of the gene or genes responsible would have been lost from the population over time through lower rates of homosexual procreation in contrast with higher heterosexual procreation rates.
This video is super helpful I watched a few other videos and it helped me pass my science test with 51/60! That’s the highest score I’ve ever got! So thank you soo much
