More DNA means more complexity, right? Scientists say not necessarily! Why is that the case?

World's Oldest Known DNA Discovered
news.discovery.com/earth/weath...
It won't make Jurassic Park a reality, but scientists have discovered 419 million-year-old DNA intact inside ancient salt deposits. The genetic material, the oldest ever found, belongs to salt-loving bacteria whose ancestors may have been among the first life forms on Earth.”
World's Largest Genome Belongs to Slow Growing Mountain Flower
www.telegraph.co.uk/news/scien...
“It is an unremarkable and rather fragile plant, but a flowering herb that frustrates gardeners for being notoriously difficult to grow has stunned scientists after they discovered it has the world's largest genome. The DNA contained within Paris japonica dwarves all other plant and animal genomes that have been analysed so far.”
Scientists Create Smallest Known Genome to Support a Living Cell
www.scienceandtechnologyresear...
“Researchers in the United States have designed and created a synthetic cell which is able to survive and replicate itself with just 473 genes, potentially leading to the development of innovative new drugs, antibodies and fuels. In a landmark for biological understanding, the scientists based at the J Craig Venter Institute of La Jolla, California, whittled away the genes of the bacterial Mycoplasma chromosome until they reached a minimum set required for life and replication.”

@lohphat 8 лет назад

Any programmer knows that timing of functions is very important. So having base pairs which seem unused may be timing/delay functions which modulate gene expressions elsewhere.

@ville307 8 лет назад

I took a genetic engineering course and our teacher always corrected us when someone said that the introns are not useless, they just do not affect the coding as far as we know it. :D

Introns are important, they allow the alternative splicing tô happen. Also, he is not talking just about the introns, but the non encoding sequences out side the genes

@zachcrawford5 8 лет назад

I'm sure that most of the "junk" DNA serves valuable functions. Some of it may only be active for a few vital hours during embryonic development, never to be active again. Also, at the molecular level, plants and other "simple" organisms can be more complex than us.

@treymiller5736 6 лет назад

Zach Crawford they may also only become active if our circumstances change. Chemicals in the air, Air pressure what we are eating and so on birds have been found that if we stop their dna from letting them grow a beak they some how get a jaw full teeth. Which takes us to wonder why birds use to have teeth yet them have beaks today.

@Toastmaster_5000 8 лет назад

It's a lot like programming - a program might involve 50k lines of code, but remove all the comments, white-space, redundancies, and inefficient methods and you might be able to reduce it to less than 20k.

@JerehmiaBoaz 8 лет назад

+Peter Schmidt A version control system might be a more accurate analogy. It's not the comments etc. but all the old, unused code still lingering in the archives.

@natr3753 8 лет назад

I suspect it's more like compiled code, but we don't understand the processor's instruction set or the architecture so we change a few bytes and observe what happens. A small number have a measurable and repeatable impact, others produce horrible crashes, and most don't seem to do much of anything we can discern but with a program with gigabytes of instructions maybe we just haven't found that set of circumstances call into that code in the lab yet...

calling non-protein coding dna "junk dna" in 2016 is embarrassing.

@luanamacagnan6128 8 лет назад

Agreed

@1stGruhn 8 лет назад

+ddarhe totally agreed! We have only just begun exploring what dna does. We have no basis for calling anything about it junk. We know so little.

@AK-gu4jq 8 лет назад

+ddarhe Read "Junk DNA" by Nessa carey to find out. Absolutely. Those non protein coding genes serves for a LOT of fonctions in the genome. Like producing RNA's or controling the expression of protein coding genes. They are EXTREMELY important and a fault in those regions can cause severe deseases.

@husriahusria8267 11 месяцев назад

Previously, it was thought that a significant portion of the human genome consisted of junk DNA. However, recent research suggests that a larger portion of the genome may have functional elements than originally believed. The Encyclopedia of DNA Elements (ENCODE) project, for example, has identified various functional elements in the non-coding regions of the genome. It is difficult to give a precise estimate of the amount of junk DNA in the human genome because our understanding of the functional elements and non-coding regions is still evolving. Therefore, it is more accurate to say that the percentage of the human genome that is considered junk DNA is currently uncertain.

Please write down the numbers you talk about, numbers are specially hard to understand for non natives. By hard I mean we have to pay extra attention to "decifer" them. It is something like metric system vs imperial (that you already cover, good job there).

@bobyong8662 8 лет назад

Having more junk DNA so that mutations are less likely to occur on useful DNA is like buying two ice-creams just in case one melts. Decaying follows 1st order, not zero order kinetics.

@AEther0238 8 лет назад

I hate to disagree (not true) but by increasing the size of the DNA you also increase the chances a mutation will occur. If you do a lot of steps you have more area to go wrong. I assume there's a % chance that something will mutate per nucleotide and adding more useless nucleotides wouldn't per say make the other useful. It's possible that those genes possessed some use for our ancestors (as you said) and simply mutated out through chance. And, I don't know about you, but I'm unaware of anyway to remove genes from a genome. If each gene codes for a new amino acid then in theory things with more genes are more complex, but that's not true if the genes are turned off. My opinion is that it's just easier to turn the genes off then go to the work of removing them. It would explain why incredibly simple organisms have incredibly long genomes, but that is 100% a guess. What do I know?

@DanceSeek 8 лет назад

Just have to point out a logical fallacy in the monologue. There is a certain percentage chance that any base pair will spontaneously mutate. Having more DNA around doesn't change that percentage at all. Think about it ... raindrops fall randomly on your sidewalk. Does having a bigger sidewalk make it less likely that raindrops will fall on the part where you walk?
