In Which Molecule is the Occurence of Mutation Most Likely

Question

In which molecule is the occurence of mutation most likely to be detected and repaired?
A)Single stranded DNA
B)Single stranded RNA
C)Double stranded DNA
D)Protein
E)None of these is an information storage molecule

Accepted Answer

Double stranded DNA is the molecule in which the occurrence of mutation is most likely to be detected and repaired. This is because the pairing of the two strands allows for the detection and correction of errors that may occur during DNA replication or repair mechanisms. Single stranded DNA and RNA are more prone to mutations as there is no template strand for error correction, and proteins are not molecules involved in information storage.
