Detailed explanation-1: -An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication. This can happen when the replicating strand “slips, ” or wrinkles, which allows the extra nucleotide to be incorporated (Figure 2). Strand slippage can also lead to deletion mutations.

Detailed explanation-2: -Insertion An insertion, as related to genomics, is a type of mutation that involves the addition of one or more nucleotides into a segment of DNA. An insertion can involve the addition of any number of nucleotides, from a single nucleotide to an entire piece of a chromosome.

Detailed explanation-3: -A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. A DNA sequence is a chain of many smaller molecules called nucleotides.

Detailed explanation-4: -Definition. A point mutation occurs in a genome when a single base pair is added, deleted or changed. While most point mutations are benign, they can also have various functional consequences, including changes in gene expression or alterations in encoded proteins.

Detailed explanation-5: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.
