Detailed explanation-1: -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-2: -The four main types of structural chromosomal aberrations are deletion, duplication, inversion, and translocation.
Detailed explanation-3: -Frameshift mutation is not a chromosomal mutation instead it is a genetic mutation in which the reading frame of DNA shifts due to addition or removal of gene.
Detailed explanation-4: -Insertion Mutation Examples For example, some diseases caused by insertional mutations include: Fragile X Syndrome. Huntington’s Disease. Myotonic dystrophy.
