Vedclass · Answer

(D) Statement $I$ is correct: $RNA$ is synthesized from $DNA$ through the process of transcription.Statement $II$ is correct: $DNA$ is more stable than $RNA$ because $RNA$ has a $2'-OH$ group on the ribose sugar,which makes it more reactive and susceptible to hydrolysis.Statement $III$ is correct: $RNA$ can act as a catalyst (ribozyme) in certain biochemical reactions,such as in the ribosome during protein synthesis.Statement $IV$ is correct: $DNA$ is more stable and resistant to mutations because of its double-helical structure and the presence of complementary strands,which provide a template for repair mechanisms.Since all four statements are correct,the answer is $4$.
