$RNA$

Vedclass · Answer

(A) The $RNA$ world hypothesis suggests that $RNA$ was the first genetic material. $DNA$ is considered to have evolved from $RNA$ through chemical modifications. Specifically,$RNA$ is less stable due to the presence of a $2'-OH$ group on the ribose sugar. $DNA$ evolved from $RNA$ by the reduction of the $2'-OH$ group to $H$ (forming deoxyribose),which makes $DNA$ more stable and suitable for long-term storage of genetic information.

The evolution of $DNA$ occurred through the chemical modification of which molecule?
