How does a deletion mutation differ from a substance mutation?

Answer;

A deletion mutation completely destroys a nucleotide, but substitution mutation replaces a nucleotide, or one amino acid.

Explanation;Deletion is an example of a Frame shift mutation, a mutation that shift the reading frame of the genetic message by inserting or deleting a nucleotide.A deletion mutation occurs when part of a DNA molecule is not copied during DNA replication. Deletion of a nucleotide in a DNA sequence that causes a frame shift mutation which usually produces a malfunctioning protein.Substitution Mutation occurs when one nucleotide base is replaced by another. There are three types of substitution mutation namely; Missense, Nonsense, and Silent mutations.

Negative responses protect our body by taking the deviation and making it less harmful to the body. When you cut your finger and lose blood, negative feedback kicks in to slow and stop the flow of blood.
