Quizplus · Accepted Answer

A single base pair substitution can cause a change in the amino acid sequence, resulting in a different protein being produced. It can also affect the amount of protein expressed if the mutation occurs in a regulatory region of the gene. Additionally, it could lead to an alteration in a gene that codes for a nontranslated RNA, leading to changes in gene expression. Finally, a single base pair substitution can lead to changes in the timing or location of gene expression during development, resulting in a novel phenotype. Therefore, all of the given choices are possible consequences of a single base pair substitution.
