Answer 1

Answer:

• Mutagens and meiosis are two sources of mutation.
• A single-base insertion is more harmful than a single-base substitution.
• Mutations can be useful to the organism.

Explanation:

• Not all mutations are harmful. Some mutations are helpful too.
• Insertion leads to a change in the reading frame which in turn changes the amino acid sequence of the protein from the point of mutation, whereas substitution changes only one amino acid in a protein.
• Deletion leads to a change in the reading frame which in turn changes the amino acid sequence of the protein from the point of mutation.
