If Evolution is true, how did DNA code itself

This was a question posed to me the other day.

What do the great people of JPP say?

What a great question lol!

Problem is it conflates two different parts of science. Evolution assumes the preexistence of DNA: that is, without a means for traits to be passed on from generation to generation there is no evolution.

So basically the question [and it's a nagging one] falls under the rubric of abiogenesis.

If there was a prebiotic world, it was a world without evolution. But in order to keep philosophic materialism afloat, there had to be a mechanism that would produce self-replicating chemicals. Then these would [somehow?] be subjected to a form of natural selection which would go on to produce the first living things. Ostensibly, the first single celled organisms.

Perhaps then, some of these would produce parasitic flat-worms which would then evolve into socialists.

At any rate, it's a great question. DNA is a fascinating biochemical, that can only be understood as a code---a computer code. They even call the three nucleotide bits of information 'codons'.

There is every chemical reason for DNA to NOT exist, yet it does. It is an enigma.

The topic question puts cart before horse.

When Watson & Crick revealed chromosomes, and realized their role in cellular multiplication, it promoted our understanding of biology.

But it's a mistake to think humans use DNA the way a cassette deck uses an audio tape.

Wilson put the lie to that.

The fact is, it's the DNA that creates us.

It's a competitive world. We compete for the best spouse, the best job, the best car, the best house, the best college, etc.
But Wilson explained that it's not really humans competing. It's our DNA that has us compete, much the way nations provide the Olympic games with competitors. The competitors compete, but it's the nations that are competing against one another.

DNA competes, with the simple purpose of proliferation. DNA not suited to the competition can end up a terminal branch in the family tree.
It's the successful DNA that tends to propagate. The Dodo is dead.

BUT !!

There may be more humans alive today than have died. That's why it's called a population explosion.

Your answer denies the existence of the horse and claims the cart pulled itself......if DNA created us, then DNA existed before anything living existed.....automatic logic fail.....

DNA is the building blocks of all living things.

As evolution progressed, those with defective DNA didn't survive or advance very far up the scale.
But then you have to tie in cataclysmic disasters and those who were so specialized, that they couldn't adapt to significant changes.

How did a living thing manage to have nondefective DNA and survive in the first place.....

The typical anti scientific religious response...

Thee is every reason for DNA not to exist? Lmao. By that Thinking there is every reason for nothing at all to exist. Please do list several reasons that DNA should not exist that would not apply to your garage door or a can of soup.
 
Nonsense. Complete nonsense. DNA coding is nothing comparable to computer coding and it's been proven a long time ago that both amino acids and nucleic acids can be synthesized via abiotic processes and amino acids via inorganic synthesis and self replicating nucleic acids existed in quasi life forms, like viruses, before DNA existed so it's very probable that DNA evolved from those Nucleic Acid analogues.

With abiogenesis, we can trace life back to amino acids, which are the smallest building blocks of DNA needed for the process of evolution. Not sure how we got to amino acids, though.

Abiogenesis explains how you get building blocks......unfortunately for your argument, that is its end point......it gives you nothing about how the blocks turn into a building

I'm not sure I understand your question. It's very vague. Do you mean "how does DNA replicate it self?"
Self replication is part of what makes Nucleic acids biologically significant and the laws of genetic inheritance possible.

Or are you asking how does DNA sequencing work or why does DNA know how to sequence base pairings that provide the information for specific protein synthesis? I. E. How does DNA code for proteins?

It's really an odd question to answer scientifically as science doesn't deal with absolute truths but what are facts to the best of our knowledge. The question was like asking "If gravity is true than how can a plane or a bird fly?"

The facts and laws of nature supporting biological evolution are as well known as those of gravity even if we don't know everything about either.

So for the sake of argument can you clarify your question as DNA doesn't "code itself" DNA "copies itself". It codes for proteins. Which are you asking?

I would argue that the person asking the question does not understand either evolution or genetics as DNA does not code itself. It codes for proteins. That makes protein synthesis possible. DNA also self replicates. That makes genetic inheritance of the protein coding function of DNA possible. That link to biological evolution is clear via the biological law of inheritance and the biological law of variation.

The question is obvious....where did DNA come from?.....

Your question is philosophical and religious not scientific. "Why is stuff here"

Obviously science has not replicated making biological life. I understand your desire to make sure the cloud guy is front and center in filling that gap in scientific knowledge.

Amen, hobgoblin!.....
 
Abiogenesis and Evolution are two different topics.

DNA codes itself by accident. When it makes a mistake replicating itself, it creates a new DNA sequence.
 
Going back to the original question. That question is nonsensical as DNA does not code itself. It codes for proteins and no Darth biochemical coding is nothing like electronic binary computer coding.

As I've already pointed out glycine was detected, in the cloud surrounding Comet 67P/ Churyumov-Gerasimenko, by the Rosetta spacecraft.
