Mutations Flashcards
(8 cards)
1
Q
Mutation
A
Heritable change in DNA
2
Q
Point Mutation
A
Usually only alters a single base pair
3
Q
Silent Mutation
A
No effect on the polypeptide
That’s is because of synonymous codes
4
Q
Missense Mutation
A
Changes how the codon is read
I.e. UAC (serine) vs UGC (glycine)
5
Q
Nonsense Mutation
A
Loses coding potential
Premature stop codon
6
Q
Frame-Shift Mutations
A
Insertion (premature stop)
Deletion (extensive missense)
7
Q
Base Substitution Mutations
A
Silent
Missense
Nonsense
8
Q
T/F
A nonsense Mutation in a proto-oncogene would be likely to create an oncogene
A
False
The Mutation would need to be one that activates
