A
addition
deletion
substitution
inversion
translocation
duplication
2
Q
what is an addition mutation
A
where one or more base is added
3
Q
what is a substitution mutation
A
where one or more bases are substetuted for anouther
4
Q
what is a deletion mutation
A
where one or more bases are deleted from genetic code
5
Q
what is a translocation mutation
A
where sequence of bases is moved from one location to anouther
6
Q
what is an inversion mutation
A
where sequence of bases is inverted
7
Q
what is a duplication mutation
A
where one or more bases is repeated
8
Q
what is the significance of a mutation
A
- can cause errors on dna replication
- can alter tertiary structure of protein
- can code for entirely different amino acid
9
Q
what is the effect of an addition or deletion mutation
A
- causes a frame shift
- means change in tertiary structure
- alters genetic code and base sequence meaning alternate amino acid could be coded for
