Question

were rRNA born perfect?​

Answer 1

Answer:

A segment of DNA that does not code for protein and has no significant regulatory role is free to change at a rate limited on by the frequency of random error.

In contrast, a gene code for a highly optimized essential protein or RNA molecule that cannot alter easily.So, when mistake occurs then faulty genes are almost always eliminated. Genes for this later sort and are highly conserved.
