What would result from a single nucleotide deletion (point mutation)within the coding sequence of a structural gene?
A)a silent point mutation with no deleterious effects
B)a missense point mutation resulting in the change of one amino acid
C)a nonsense point mutation resulting in the generation of a premature stop codon
D)a frameshift mutation,producing a completely different amino acid sequence
E)All of the choices are possiblE.

A single nucleotide deletion within the coding sequence of a gene would result in a frameshift mutation. This type of mutation alters the reading frame of the gene, leading to a completely different amino acid sequence from the point of mutation onwards.
