RNA was likely replaced by DNA as the genetic molecule in most organisms because
A)RNA is less stable than DNA.
B)RNA has a higher chemical stability.
C)RNA errors are more easily corrected than DNA errors.
D)A and C
E)All of the above

Question

Quizplus · Accepted Answer

RNA is less stable than DNA, making it more prone to damage and degradation. DNA's double-stranded structure also allows for better error correction during replication, making it a more reliable genetic molecule. The higher chemical stability of RNA mentioned in option B is not a reason for why DNA replaced RNA.
