Question

Genetic mutations are

• A. more common in bacteria due to their extremely rapid rate of DNA replication
• B. permanent changes in the base sequences of a gene in the DNA strand
• C. due to errors in DNA replication
• D. all of the above

Answer 1

Answer: (D)

all of the above

Mutation is a permanent change in the genetic material of a cell of a living organism or of a virus. It results in the change of nucleotide base pair(s) and genes they are part of. There might be different causes of mutation, for example, any error in DNA replication during cell division results in a mutation. Faster is the rate of replication and reproduction in organisms, more frequently they undergo mutation which is seen in their descendant population as these mutations become a permanent part of their genome which is transferred to progeny cells.

So, the correct option is 'all of the above'.
