    The idea I was going with is DNA is a hoarder; for onions it's like the house full o' papers and junk; for pufferfish their DNA was decluttered and for us, we're at the drawer stage in the kitchen or room stage in the house where there's lots we might need and we've kept. Some of it is the inevitable plastic bag drawer, the old screw jars, the lego box the kids had when they were young, some of it is the copper wiring that could be used to put up the fairy lights in the patio we just have not got round to, or the sound system that's to go with them. I'm really impressed with all the coding analogies; you guys just rock.

  • @urbanelemental3308
    @urbanelemental3308 6 лет назад +19

    The existence of junk DNA happens in Genetic Algorithms as well. As genomes are mutated and bred, some very successful genomes (organisms) carry 'code' that isn't used or has no effect on the functional result when there are a limited set of input parameters. These typically will weed themselves out over time if the evolutionary engine places value on shorter genomes and more efficient code. But throwing around 'junk' in the evolutionary process is part of what makes it work. An organism in nature might have 'junk' that isn't functional for 'today', but might have been useful in the past and may be useful in the future. It's even possible that an organism has experienced cyclic reactivation of portions of the genome as conditions in the environment change.

      It mainly boils down to what "functional means". You can get up to 80% of the dna if you use functional loosely. Or you can get a very small amount if you use function specificly. Another thing why people are angry is because if it is proven that most or all of our dna is useful then creationists get a big score and evolution gets a big hit.

      I know you joke (or do you?), but it's pretty common to have an expansive slew of dead genetic info stripped from the corpses of viruses that once attacked your body and planted into the sequence as a reference tool for future use. Basically, that section of your DNA is an encyclopedia your immune system and such can refer to whenever it meets a new viral infection and plan its attack accordingly.

    A concept I picked up from "The Extended Phenotype" by Richard Dawkins, was the evolvibility of a species can be a trait that natural selection can work on. So all that junk DNA can lend variable traits to a species by copy/paste mistakes in the DNA. The more mistakes that junk DNA makes, the more variation in the species, the more apt a species is to evolve, therefore giving that species a leg-up in adaptability.

    Some "junk" genes can also produce small, noncoding RNAs that work to break down mRNAs as a method for controlling gene expression through a process called RNA interference, which is an interesting mechanism. Speaking of which, could you do an episode about RNAi? I may be biased, since I've done some undergrad research into it, but I think it could be a very interesting topic.

    I remember thinking as a student that junk DNA could simply serve as a statistical target for random mutations. If most of your genome was functional, then a random mutation would be more likely to change an important gene, likely leading to problems. However, like a game of battleship, if most of your genome is junk, then it is less likely that a valuable gene will be hit by a random mutation.

    • @LeonMustapha
      @LeonMustapha 6 лет назад +3

      For that to be the case, there would need to be some mechanism that increases mutation rate in a larger genome (which may well be the case). Otherwise it would be like expecting your car to be less likely to break down when you park it in a car park with loads of other cars in it.

      No matter how much DNA you have, the mutation rate of your genes will stay exactly the same. Not to mention that the prime way of developing new traits, is not random mutation, but gene duplication and modification, for which some junk DNA to be embedded in indeed helps.

    @Locut0s 6 лет назад +1

    Fascinating. So it sounds like perhaps the large regions of “junk” DNA might be an evolutionary survival tool against the natural processes of random mutation? Mutation of course, along with natural selection form the engine that drive evolution. Although actually I think the majority of evolution doesn’t come from natural selection operating on mutation rather natural variation of “normal” traits. But mutations will be random and the vast majority bad, so it sounds like perhaps junk DNA might be a survival tactic in the same way as building a spacecraft that’s 80% nonfunctional would be protection against micrometeorites ?

    Dear SciShow Team. First of all, thanks for all your interesting and informative videos which I believe take a lot of time and effort to be researched and created. I found, in comparison to many other "Science" Channels, that you don't jump to conclusions easily but keep it straight to information and facts. Great job on that.
    I follow your channel for quite some time now as I am teaching fundamental science and it gives me an opportunity to update my own knowledge to provide only the latest facts for my students as textbooks often fail to stay on top of certain topics as they are updated way too fast. As you know, it is quite a difficult and time consuming job to keep ourselves updated about science by roaming through journals and websites, which in some cases, are not very trustworthy either. So a very big Thank You guys for doing this.
    Now my question. As I understand it out of your video, you consider the left-over DNA from evolution, as part of Junk DNA. As far as I have learned and also teach, it is called 'Ancestral' DNA, isn't it? Am I mistaken here? Please shed some light into my dilemma.
    Thank you a lot in advance.

    From where I am from -as far as I know- back then (some 50 years) those industrial birth rates of ~15 kids, required for a population to be able to maintain some 80% of its genome functionally active, were not that rare to find.
    My core family is small in number, particularly. However, many of my closest relatives are almost right there, near the mentioned rate. In one family, there are 11 cousins. Others have around 8 or 7 kids. Moreover, my father equally grew up in a house of 10 brothers and sisters.
    Knowing of many other families that, back there, were big numbered, too, I wonder how far back this tendency goes on. Also, how this could affect, if at all, the genetic relationship inside the society I live on? Any idea, anyone?

      Might be handing having partly coded dna ready to be made into something useful, in case we need it. Could be part of the development process of new useful stuff. Partly completed job that didnt go anywhere at the time, but may be ready to go quickly when conditions change...

    Nothing more frustrating than pyrosequencing what you're sure is an oncogene only to find out it was in a noncoding region. Thank gourd for adaptive Informatics and next-gen

    I remember hearing a thing in regards to certain plants having more genes than us: "can you survive having huge chunks of you removed and just grow them back? Can you live in the harsh elements with no protection? Can you last months without food or water? Etc."
    Like with an onion.... You can take the onion plant out of the ground, cut off all the shoots/leaves and roots so it's just the bulb, then store it in a cupboard or fridge for months (so no food or water for the onion)... And it'll still grow. Sometimes on its own, but otherwise just by sticking it in some soil.
    Humans can't lose most of our body and then be deprived of food and water for months and still remain alive. So like. I think it makes sense? Onions are more incredible than people give em credit for.

    According to current data there are some families/subfamilies of transposons that are still moving in the human genome (Alu) not to mention that transposons play a huge role in gene evolution and speciation

    I grew up as a hypoglycemic child and at age 20 it was discovered that I have zero working insulin receptors which caused the multitude of problems including putting me in a wheelchair! The technology is there now to either splice this Gene out or fix it but my research team in Boston seems to have been ignoring me since 1994. Disgraceful!

    It would help your team of scientists if they had a few engineers in the mix. The engineers would tell you - haven't you ever heard of boot-up sequence or code? A heart cell isn't a heart cell just yet, but a chunk of them somehow with bio-molecular magic, know both when and where to become one.
