Beyond Mendel : the chromosomal theory of inheritance (an animated lecture video.
Переглядів 16 тис.6 років тому
While Mendel's research lay in the scientific abyss for 35 years, the rediscovery of Mendelian genetics marked the beginning of modern genetics around the turn of the 20th century. Following the rediscovery of what became known as Mendel's laws of genetics, an explosion of research into hybridization blossomed leading to the discover of the importance of chromosomes in inheritance. Emerging und...
Mendel and the Gene (an animated lecture video)
Переглядів 26 тис.7 років тому
The animated lecture video serves as an introduction to Mendelian Genetics. Designed for collegiate level introductory science classes, topics include: particulate inheritance, blending inheritance, Mendel's laws (I prefer to call them principles) of dominance, segregation and independent assortment, as well as an introduction to pedigree analysis, and a discussion of the historical context for...

❤❤❤❤
very nice explanation and also the animation, it helps me a lot to understand about the central dogma.
Thank you for the brush ups i remembered that.
the nerd is delicate.
.1 covelance then nist right?
ribi corp x 2
the sinless clean asset clarity is not false.
This is really helpful, thank you.
Best
thank for nailing it home. the best ever explanation of central dogma. hoping to understand more💪
Very clear and informative.
The base sequences which code for proteins do NOT code for what the protein actually does. The sequence only specify which amino acid is added next in line. The magic happens when the various properties of each a.a interacts with water, metallic ions, chaperone proteins, and hydrophobic and philic regions. If structure can never become code, how can prebiotic evolution sort between useful and useless naturally occuring functional peptides?

4:32 Electrons' are virtually massless, so their masses aren't included 4:51 - mass of a proton or neutron is 1.67 × 10²⁴ grams. in terms of amu, it's almost 1 amu.
5:07 5:22
A great video, but seriously guys, why have you at 13.36 a picture of Barbara McClintock instead of Rosalind Franklin?
26:37 It is not correct to say that the overall structure of a fully-functional protein is know as the quaternary structure. Many proteins are fully functional even though the have only a single polypeptide chain, so have a functional tertiary structure (and don't adopt a quaternary structure).
21:48 Malaria is not a parasite, it is a disease. That mistake seems like just a typical "brain fart" or slip up, that we all have, because you go on very soon to say that malaria is a disease.
21:36 Sickle-cell anemia is not advantageous. You are confusing a disease condition for an allele. Sickle cell anemia is a disease in people who are homozygous for the sickle cell allele: humans have 2 copies of the gene, and homozygotes have both of their versions as the mutated, sickle cell allele. That is not advantageous. A heterozygous person has one sickle cell allele and one "normal" allele: such people do not have the disease sickle cell anemia. They are carriers for the disease, but they don't have it. In regions where malaria is prevalent. 1) Being homozygous for the sickle cell allele would mean having the disease sickle cell anemia, which is bad. 2) Being homozygous for the "normal" allele means the person has none of the protection against malaria that the sickle cell allele provides, which is also bad for the person. 3) Being heterozygous provides the best of both worlds: the person does not have the disease sickle cell anemia, and does get some protection against malaria. This is the classic example of heterozygote advantage.
11:05 DNA does not synthesize RNA. DNA is a passive molecule. It is a protein (RNA polymerase) that synthesizes RNA, using DNA as a template.
8:37 You have the reaction, and result, wrong. The bond is formed between the 3' hydroxyl group of the top nucleotide, not the hydrogen of the 3' carbon. After the phosphodiester bond has formed, the 3' carbon of the top nucleotide should have a hydrogen remaining, but you show it having a hydroxyl group. And you show the carbon directly bonded to the phosphorus atom, but there is actually an oxygen atom between the carbon and the phosphorus.
10/10 video
Bravo 🙌🙌
This is sooooo amazing. The concepts and the linkage between the discoveries of various scientists. Thank you so much for this.❤️❤️
Glad you enjoyed it!
This is great for my Botany course, but also all other sciences and engineering too. Thank you!
You're very welcome!
Awesome 👍🏻👍🏻It was a wonderful lecture
Thanks a lot
Well written and the visuals are so amazing. One of the best lectures in the basics of chemistry
This is one of the best videos I have seen on chemistry basics - even compared to Khan Academy which was also a superb set of videos. However isn't formation of water an exothermic reaction? at time 16:00 in the video
So when you talk about the nuclear force that binds protons and neutrons together within the nucleus how is this force generated? Where exactly does it come from?
Thanks for the video
Great video. Pretty sure that is Barbara McClintock not Rosalind Franklin though.
I'm glad someone else noticed this. The image was put on the screen and immediately I thought, that's Barbara McClintock!
Im hoping this is correct because im using it for my science lab
Same!!

This is the clearest explanation I can find. It really helps that this has subtitles. I can share this to students in my Biology class.
Very nice. I also loved the ending. People (scientists) were falling for Darwin's no-proof story telling (aka pangenesis) while Mendel was discovering real facts. Lesson learned. Never believe someone for their reputation, instead look at the facts. Science 101.
I like the “Riders on the Storm” harpsichord or piano cover intro
I hear rain falling...
Wow, so much wow.
NOT BY ACCIDENT. Evolution = Self Assembling Atoms = Impossible ==== Why are there so few viewers? This should be mandatory viewing for all of the pseudoscience evolutionists. ==== Evolution = Self Assembling Atoms = Impossible =====
WOW THANK YOU FOR THIS VIDEO, IT MAKEES ME INNERSTAND A SCENE IN THE MATRIX WHEN MOPHEOUS HOLD THE BATTERY IN HIS HAND.
Awesome !!!love this lecture thanks 😌😌
wow . From a mathematical point of view we are engineered. Too beautiful, too perfect to be random just wow.
Nice. A lot of content on this one. I already took statistics and I see how the points made in this video are very well connected.
Very nice explanation.Thanks
Best video on the central dogma of life I’ve ever seen 🤞🏾🤞🏾👍👍👍
Bravo!
Do more videos🙏
This is an amazing lecture ,100 out of 10. The pace of the lecture lets us grasp easily. Well done
Nice video
