Question

Deleting or inserting a nitrogen base in DNA causes what type of mutation?

Answer 1

Answer:

One type of frameshift mutation is called insertion. As the name implies, an insertion occurs when a single nitrogen base is accidentally added in the middle of a sequence. This throws off the reading frame of the DNA and the wrong amino acid is translated.

Answer 2

Answer:

A point mutation that occurs when a single nucleotide base is removed or added within a DNA sequence is known as a frameshift mutation. These mistakes, made by DNA polymerase during the replication process, can be detrimental as they directly impact the amino acids coded for within a DNA sequence.
