Point Mutations

Question

Point mutations
A)are due to a change in one DNA nucleotide.
B)may change a specific codon.
C)can cause a genetic disease such as sickle-cell disease that is due to a base change that codes for valine rather than glutamate.
D)All of the choices are correct.

Accepted Answer

Point mutations involve a change in a single nucleotide, which can alter a specific codon and potentially lead to genetic diseases like sickle-cell disease, where a base change results in valine being coded instead of glutamate.
