Question

Compare and contrast nonsense mutations with suppressor mutations.

Answer 1

Nonsense mutation refers to a point mutation which results in the appearance of a stop codon and thereby results in premature termination. This kind of mutation leads to the formation of truncated and non-functional proteins.

Suppressor mutation can be referred to as a second mutation that counters the effect of the previous mutation and reverts to the original phenotype. This type of mutation can be seen as a mutation that rescues the phenotype.

nonsense mutations affects the phenotype by producing a non-functional protein, on the other hand suppressor mutation rescues and restores the original phenotype.
