Question

What is one way that a frameshift mutation could occur? (1 point)

O three nucleotides are inserted
O two nucleotides are deleted
O three nucleotides are deleted
two nucleotides are substituted

Answer 1

two nucleotides are deleted

Step-by-step explanation:

I just did the quick check and the answers are:

1. Mutations affect protein synthesis which impacts the way traits are expressed

2. Substitution

3. Substitution

4. food availability

5. two nucleotides are deleted

Answer 2

two nucleotides are deleted

Step-by-step explanation:

Frameshift mutations arise when the normal sequence of codons is disrupted by the insertion or deletion of one or more nucleotides, provided that the number of nucleotides added or removed is not a multiple of three.

Because two nucleotides are deleted (2 is not divisble by 3), it would be a source of a frameshift mutation.

Hope this helped! :^)
