Which statement best supports the rna world hypothesis? dna molecules are a precursor to self-replicating rna molecules, which are used to build proteins. early rna molecules were able to self-replicate, which to explain why all organisms share the same genetic code. simpler self-replicating organic molecules preceded rna and contain genetic information. the absence of oxygen in earth's early atmosphere allowed for proteins to catalyze the production of new rna molecules.

I just took the test for this, I got it wrong, so I know it isn't the DNA molecules are a precursor to self-replicating RNA molecules, which are used to build proteins. But know I think about it, it's probably B.

Explanation:

The correct answer would be the second option.

RNA hypothesis suggests that RNA used to serve as the genetic material in early cells or life.

It is supported by the facts that:

RNA molecules were able to self-replicate which helped in passing the genetic material to the offspring.

In addition, RNA had catalytic activity by which it could catalyse various reactions.

It makes it more susceptible to mutations which led to the evolution and production of DNA.

okay now i don't know this but for the pints nothing else to say bye
