    Mostly excellent. Except...at the beginning, he refers to the sugar phosphate backbone and then the nucleotides in the middle of DNA strands. Misleading - nucleotides are made up of bases, sugar, and the phosphate group (i.e. bases attached to the sugar-phosphate backbone). Just wanted to note that since we all have picky professors : ). Thanks for posting, this was otherwise very clear.

    Greetings everyone. Let’s see if I can clarify some of this terminology.
    DNA is a chemically based memory system. All memory systems are information storage machines. They all have hardware (a structure of physics particles), and software (the memory contents = pure information) components. Information stored in any memory system is called “software”. All hardware and software systems exist separately in a highly decoupled manner. So the software is separate and independent of the DNA hardware. You don’t need to talk about DNA chemistry when discussing the genome (just like you don’t need to know how paper and ink work in a book, to understand its contained story).
    The genome is a software system stored in the DNA memory system. That software provides the intelligence at the core of all cells to manage cellular activities. Eukaryotes simply have a better cellular computer, so they have the power to handle the added complexity of maintaining multi-cellular forms. This is why the Cambrian explosion occurred. There is a big difference in complexity between simply managing a pool of cells, and the construction and maintenance of a multi-cellular organism (like plants, fungi, and animals).
    Thanks for listening.

    • @Thefamiliaguy
      @Thefamiliaguy 10 років тому +17

      dargo rito Yep I know. I was just making a computer data technology analogy. There are many similarities between biological organisms and computer systems. There are things like DNA code error correction to help maintain the integrity of the DNA. Core DNA passed on through reproduction is stored in protected areas in the body like offsite data backup. There is DNA that works like software programming logic that decides when and how to express a gene. Genes themselves are like data maps of the design of each protein. There is processing like a CPU inside each cell. There is network communication between cells I think with hormones. There are network firewall similiarites with a membrane surrounding a cell that protect it by blocking some things out and let other things in. Organisms are full of sensory input and of course produce output in the form of sound/voice and body motion. The overal organisms have high level software capabilities like analytical skills just like software performing analytical reports. Humans have cpu/brain that peforms information processing. We have different types of memory storage just like data stored and used by applications. We have major systems in the body that integrate with each other and includes overall system processing workflow. We have sleep mode like computers :-). We can get a virus just like a computer. Computers run on code that is based on different levels of voltage and biological life runs off of code represented with 4 different chemicals. So computers in essense run on code in binary and life runs on quinary code. Data can get corrupted on both. There are probably many more similarities that are not coming to mind right now. Though the big difference with biological life is that computers yet can't reproduce and evolve themselves on their own but they do reproduce by the market choices we all make that cause a form of market selection and the evolution of newer advanced computers that engineers design to meet these market needs over time. I just find it very interesting how our engineering efforts in technology ended up matching the design found in life in so many ways.

    A nucleotide can't be arranged along the sugar-phosphate backbone: a nucleotide consists of a phosphate, 5 carbon sugar and nitrogenous base. the sugar and phosphate form the backbone. You're probably talking about the bases, of which there are 4 kinds: adenine, thymine, cytosine and guanine

    First we need to change the culture or our country. Instead of water cooler talk being of sports and celebrities we should be talking about the bills being introduced and passed that will impact us and the future of our children. The bowl game and celebrity tweet will not matter in 2 weeks, while a bill can still matter in 20+ years. We need to know what our representatives are doing in order to hold them responsible. If people knew the way some of our presidents voted when they were representatives, they would have never made it to president. We can play the blame game all day or we can take action. This is just a small step but it's in the right direction. #StartHere #KnowYourRep #HoldThemResponsible

    We need to put politics back on the table. All this, it's impolite to discuss politics is bull. Thats what the government wants. All of us in the dark not talking issues out together with our friends and family trying to find middle ground then finding people who can represent us as a whole. They talk about issues like gay marriage and abortion so we spilt up and say red or blue all while the politicians gather to pass the bills that steal our rights, rip away our privacy, kill our constitution, take our tax dollars for weapons that even most military doesnt want just so their big campaign contributors are happy with a new government contract, they give oil companies out our land to frack contaminating our water, polluting our air. Money shouldn't equal governmental influence, our voices as a people should be the only, I repeat, the ONLY thing to influence government. We do care about issues like abortion and gay marriage but when the system collapses due to corruption we will all wish we talked about the real issues that politicians talk about behind closed doors. Lets kick open those doors and say, "Hey it doesnt matter what you think, it matters what WE think!" And I think we all want to be heard. Why do I need to be represented, this isnt the 1800s, I dont need someone speaking for me, my voice can be heard across the country, across the world.
    I want the right to vote on bills. No more House of Representatives. That will be the next step of evolving our government. Online government forum of voting, if banks can do online banking safely we can do online voting safely. Take that X amount of billions from our budget on a non working fighter jet and create a website secure for us to have the power. They want to pass a bill, they should need to get thru us first, the people. No more shady deals, no more last second bills. We need to be our first line of defense. Lets defend this country from all threats foreign AND DOMESTIC!

      @dr.mikejohnson571 8 років тому

      +John Schaeffer Problem is that liberals don't deal in reality....they live in a fantasy world where facts and logic based on those facts gives way to horribly misplaced and misdirected feelings. They also "believe in" propaganda created by liberal leaders and peudoscientists. So the discussion then becomes meaningless when it is impossible to establish a fact base people can agree on. Right now: Gun control. Liberals believe they can pass laws to prevent criminals from possessing and using guns to commit crimes. This is impossible. They then rant and rave about racism and how blacks are discriminated against regarding criminal activity.....the vast majority of gun violence is by blacks committing crimes....then to top it off they demand total freedom of expression....how dare anyone ban rappers from their culture of violence and hatred or stop Hollywood from depicting gun violence on a ridiculous scale........don't even get me started on the ridiculous concept of "Global Waaaarrrrrrmmmmming"......pure propaganda used to seize power from the ignorant

      DNA is the acronym for DeoxyriboNucleic Acid a long double-stranded molecule composed of subunits known as nucleotides which may have one of four distinguishing bases (Adenine, Guanine, Cytosine or Thymine). Chromosomes are made of DNA, conversely the long chains of DNA are called chromosomes. Genes are stretches of DNA (along chromosomes) that encode the information to manufacture (mostly) proteins (in some cases RNA).

      +Prophecy Who knows, that is the mystery of form. Some animals can form missing limbs, like salamander can regenerate limbs or eye parts of their tails. The information comes from the outside as well as somewhere else. Molecules are also vibrating at their own frequencies and rates, depending on the temperature, pressure :p and other factors of interests to life of cells. Exposure to lights, wind, dust, air and the starlight of venus on a particular day of the year might all influence molecules. when a seed starts growing, it gets a signal from the outside somehow. It has to be wet moist and at the right temperature plus some other factors not covered here. We are a result of the signals we receive from the outside. It is how a seed begins and there is no reason to assume that it stops when we are adult human beings from living in the 21st century. The Protein and DNA itself is the bad ass machinery we have, but the outside signal determine our course. Our being is this weird invader ghost from the outside that manipulates matter through a nervous, skeletal and muscular systems. Ha Ha! been watching them Bruce Lipton videos!
