4.3 genetic diversity can arise as a result of mutation/ during meiosis Flashcards
1
Q
what happens in genetic mutations
A
change in base sequence of a chromosome
2
Q
when can genetic mutations occur
A
during DNA replication
involve base deletion and substitution
3
Q
why do not all base substituions cause a change in amino acid
A
genetic code is degenerate so one amino acid can be coded for by more than one triplet sequence
4
Q
what do mutagenic agents do
A
increase risk of gene mutations
5
Q
meiosis
A
