Replacing an Adenine Nucleotide with a Guanine is an Example

Question

Replacing an adenine nucleotide with a guanine is an example of a
A) translocation.
B) transition.
C) transversion.
D) forward mutation.
E) reversion or reverse mutation.

Accepted Answer

Replacing an adenine nucleotide with a guanine is an example of a transition, which involves the substitution of one purine for the other or one pyrimidine for the other. Translocation involves the exchange of genetic material between non-homologous chromosomes, transversion involves the substitution of a purine for a pyrimidine or vice versa, forward mutation results in a change from the wild-type phenotype to a new phenotype, and reversion or reverse mutation involves the restoration of the wild-type phenotype from a mutated phenotype.
