1
Q
What is a mutation?
A
An alteration of the DNA sequence, oftern arise spontaneously during DNA replication
2
Q
Why might a mutation not lead to a change in the amuni acid sequence?
A
Genetic code is degenerate so mutation may end up coding for same amino acid as the original triplet
3
Q
What is a substitution mutation?
A
When a nucleotide in the DNA sequence is replaced by another. This is more likely to be a quiet mutation, meaning no change occurs in the amino acid sequence
