Question

which of the following statements regarding mutations is true? mutations are responsible for the creation of new alleles of genes. only mutations in exons can affect the amount of protein produced in a cell mutations that result in new phenotypes are always found in exons mutations are always harmful to an organism only mutations in exons can affect the amount of protein produced in a cell and mutations that result in new phenotypes are always found in exons

Explanation:

Mutations are changes in DNA sequence. They create new alleles of genes. Mutations in non - exons (like regulatory regions) can also affect protein production and phenotypes. And not all mutations are harmful; some can be neutral or beneficial.

Answer:

Mutations are responsible for the creation of new alleles of genes.
