Question

1. A mutation that causes changes in the amino acid sequence downstream of the mutation is called (1 point)
a point mutation.
a translocation mutation.
a substitution mutation.
a frameshift mutation.

Answer 1

Definitions of each mutation:

Point mutation: A mutation affecting only one or very few nucleotides in a gene sequence.

Translocation mutation: When a gene breaks off from it's sequence and goes to another one or "relocates"

Substitution mutation: Commonly used as a synonym for a point mutation.

Frameshift mutation: A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides that is not evenly divisible by three from a DNA sequence.


The answer is: frameshift mutation
