Detailed explanation-1: -An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication.
Detailed explanation-2: -An insertion changes the DNA sequence by adding one or more nucleotides to the gene. As a result, the protein made from the gene may not function properly. A deletion changes the DNA sequence by removing at least one nucleotide in a gene.
Detailed explanation-3: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.
Detailed explanation-4: -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-5: -Insertion frameshift mutation, wherein one or more nucleotides are added to the base sequence of the nucleic acid, which results in the change in the reading frame.
