Detailed explanation-1: -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-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: -(in-SER-shun) A type of genetic change that involves the addition of a segment of DNA. It may be as small as a single base but can vary significantly in size.
Detailed explanation-4: -Chromosomal insertion occurs when a segment of one chromosome is translocated and inserted into an interstitial region of another non-homologous chromosome (interchromosomal insertion), or into a different region of the same chromosome (intrachromosomal insertion).
Detailed explanation-5: -In genetics, an insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence.
