Please help if you know!

An insertion mutation usually causes more defects than a point mutation because insertion mutations
A. affect a whole chromosome
B. can affect the order of many amino acids
C. occur only during transcription
D. can be only silent mutations

Answer 1

An insertion mutation usually causes more defects than a point mutation because insertion mutations **can affect the order of many amino acids**. This is because an insertion mutation occurs when an extra base pair is added to a DNA sequence, which can cause a shift in the reading frame of the genetic code during translation. This shift can change the sequence of amino acids that are produced, potentially altering the structure and function of the resulting protein. So, the correct answer is **B. can affect the order of many amino acids**.
