Mutations Flashcards
1
Q
Mutation
A
Change in base sequence of DNA that leads to altered mRNA which can lead to altered amino acid sequence
2
Q
Substitution
A
Mutation that exchanges one base for another
3
Q
Insertion
A
Extra base pairs inserted into a new place in the DNA, resulting in base pairs after insertion to be shifted down
4
Q
Deletion
A
Section of DNA is deleted, resulting in base pairs after the deletion to move up
5
Q
Duplication
A
A section of DNA copied one or more times
6
Q
Missense
A
Single nucleotide base substitution that alters a codon so it codes for a different amino acid
7
Q
Nonsense
A
Stop codon inserted early which results in premature termination of protein
