Detailed explanation-1: -Insertion or deletion of one or more nucleotides during replication can also lead to another type of mutation known as a frameshift mutation.
Detailed explanation-2: -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-3: -There are three types of DNA Mutations: base substitutions, deletions and insertions. Single base substitutions are called point mutations, recall the point mutation Glu—–> Val which causes sickle-cell disease. Point mutations are the most common type of mutation and there are two types.
Detailed explanation-4: -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. Deletion. A deletion changes the DNA sequence by removing at least one nucleotide in a gene.
Detailed explanation-5: -Mutations can be of many types, such as substitution, deletion, insertion, and translocation.
