Detailed explanation-1: -A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand (Figure 3). Figure 3: In a deletion mutation, a wrinkle forms on the DNA template strand, which causes a nucleotide to be omitted from the replicated strand.

Detailed explanation-2: -Deletions A deletion, resulting in a frameshift, results when one or more base pairs are lost from the DNA (see Figure above).

Detailed explanation-3: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.

Detailed explanation-4: -(deh-LEE-shun) A type of genetic change that involves the absence of a segment of DNA. It may be as small as a single base but can vary significantly in size.

Detailed explanation-5: -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.
