A Mutation in a Collagen Gene is Likely to Affect

Question

A mutation in a collagen gene is likely to affect the phenotype because
A) it is extremely rare.
B) during meiosis, the chromosome that bears the mutation is more likely to enter a gamete than the chromosome that carries the wild type allele.
C) collagen has a very precise three-dimensional structure, so nearly any disruption alters the overall conformation.
D) people who use cosmetics with collagen silence collagen genes.
E) there are many collagen genes.

Accepted Answer

Collagen has a very precise three-dimensional structure, so nearly any disruption alters the overall conformation. Therefore, a mutation in a collagen gene is likely to affect the phenotype.
