DNA, Hot Pockets, & The Longest Word Ever: Crash Course Biology #11

Hank imagines himself breaking into the Hot Pockets factory to steal their secret recipes and instruction manuals in order to help us understand how the processes known as DNA transcription and translation allow our cells to build proteins.

    Catia Park It's all about how the brain takes in information. The majority of people need a slower, more in-depth explanation first, followed by quick reminders like this, if we assume that the current educational system is broadly on the right track, that is. If you just watched these without prior subject knowledge and then went for a test at A-level or degree level, you might not remember it all. However, if you have an unusual brain that is able to memorise every syllable of information crystal-clear, go for it.

    mikotorubychan It's incredibly long name is actually not a result of a bored scientist; Titin happens to be an IMMENSELY long protein strand, and there is a certain scientific formula for naming proteins. Most proteins have long names, but Titin's unusual length makes it have a longer name than usual.

    +mickeynotmouse They move and assemble via the random movement of tiny particles on their size-scale (because they're so small they're moved about by the tiniest force, absolutely everywhere, very fast and jittery) and behave according to a force of entropy (a natural force, like gravity), using up the free energy around them until they form a stable molecule. Because of the shape of some molecules, like the base pairs and amino acids, they'll only arrange in certain ways with the opposite molecule that fits them, or into an optimal (best) position/energy state. Some physics comes into the biology of understanding how the particles behave... but as to how they became this way, the most well-reasoned explaination is evolution and mutation. At the beginning of life, the theory (short version) is that chemical particles reacted to form amino acids which formed proteins that lead to the first RNA, but the evolution of cells and and how they developed these complex processes needs... a bit of a stretch of imagination.

    Have you ever wondered why the DNA contains thymine, while the RNA contains uracil? Here's an interesting fact. A spontaneous process called deamination (replacement of amino fuctional groups with keto groups) is fairly common in both DNA and RNA. As it happens, the product of deamination of cytosine is uracyl, and it is the most common of deamination processes affecting the DNA. The product of cytosine deamination (uracil) is readily recognized as foreign in DNA and is removed by a repair system. If DNA normally contained uracil, recognition of uracils resulting from deamination of cytosine would be more difficult and that would in the long run lead to a decrease in GC base pairs and an increase in AU base pairs in the DNA of all cells. Establishing thymine as one of the four bases in DNA may have been one of the crucial turning points in evolution, making the long-term storage of genetic information possible. (Source: Lehninger Principles of Biochemistry) Also, we commonly speak about introns as the junk which gets spliced leaving the ''important'' stuff for translation. Why do organisms have introns at all? It has been shown that introns are responsible for boosting expression levels of proteins up to 400(!) times (parts of DNA coding for introns include regulatory elements involved in transcription), they contribute to DNA packaging (chromatin formation), control the delay between gene activation and appearence of its protein product (which is especially important in developmental processes) and are responsible for alternative splicing. This latter process is extremely important because it allows one gene to produce multiple proteins, thereby increasing complexity of organisms without the need for occurrence of thousands of new genes. Also, many non-coding RNAs are actually products of spliced introns, such as miRNA, snoRNA, lncRNA, siRNA... (Source: www.ncbi.nlm.nih.gov/pmc/articles/PMC3325483/)

    I'm studying for the AP Bio 2020 test on Monday the 18th, so the Crash Course intro is now my personal theme song XD Also, for anyone studying (or cramming) for the AP Exam: Things are different. Things are /hard/. We've struggled all year, clawing and biting our way through the piles and piles of knowledge that class has thrown at us. But this just proves how freakin' STRONG we are! Look at all we've come through! For what feels like forever, we sleep, eat, and breathe SCIENCE. And it's gonna pay off. I promise. WE CAN DO THIS!!!!!!!!!! On Monday, we're gonna put on our comfiest clothes, grab some coffee/tea, log onto that computer, and show this world just how awesome we are!!! You might be feeling a little powerless in the face of new changes - or even in the face of the all-too-familiar enemy of self-doubt. But once you realize that there's no punishment for failure and only reward for success - that's power. Once you realize how /prepared/ and /intelligent/ you are just for making it this far already, /that's/ power. You've got this. Trust yourself to do amazing on this, and I promise you, you'll come out on top.

    "evolution......created.... machinery....information... complex machine....". since evolution is the antithesis of creation, this sentence would make sense if "God" was substituted for "evolution". It seems you are demonstrating the accuracy of Romans 1:20, Abraham "For since the creation of the world God’s invisible qualities-his eternal power and divine nature-have been clearly seen, being understood from what has been made, so that people are without excuse." Clearly you know machines are "created" - so why not acknowledge the Creator?

    Elizaveta Hedervary my atheism is being shaken by this, as well as several other elements of science. I've heard Richard Dawkins hypothesised this complex life might have originally come from, basically, ETs, seeding this planet. Intentionally, or accidentally. I wouldn't have expected that kind of theory to come from someone like him, although it seems vaguely plausible to me. Can someone please explain to me what other 'best guesses' the atheist camp have for how we could possibly have evolved a genetic code, billions of characters long that contains information to create amino acids in the exact right combination for them to actually make functional proteins? I think Steven Myer said the chance of a typical 150 amino acid long protein was 10 to the 164th power. So chance is out, natural selection couldn't account for this complexity existing from the first cell, so what do we have? Again, I was brought up an atheist, I'm not looking at science and trying to make it fit my existing religious beliefs, I don't have any, but seriously, this looks exactly like a computer code, and those surely don't come about by chance, natural law, or any combination of the two.
