Question 2

list all of the types of mutations

Answer 2

1. Substitution
2. Inversion
3. Insertion
4. Deletion
5. Duplication
6. Translocation

Question 3

define inversion
what are the consequences?

Answer 3

where a sequence of bases is revered

there is no change in the protein coding as amino acid sequence is degenerate

Question 4

define insertion

what can it lead to?

Answer 4

one or more bases are being added

can cause a frame shift

Question 5

define deletion

what can it lead to?

Answer 5

one or more bases are removed

can cause a frame shift

Question 6

define duplication

what can it lead to?

Answer 6

where one or more bases are duplicated, leading to a frame shift or genetic disease

Question 7

Answer 7

where sequence of bases is moved from one part of the genome to another
