Detailed explanation-1: -Deletion frameshift mutation: When in the nucleic acid, one or more nucleotides are deleted, resulting in reading frameshift. Insertion frameshift mutation: When in the nucleic acid, one or more nucleotides are added, resulting in reading frameshift.
Detailed explanation-2: -An insertion or deletion involving a number of base pairs that is not a multiple of three, which consequently disrupts the triplet reading frame of a DNA sequence.
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.
Detailed explanation-4: -Frameshift. Since protein-coding DNA is divided into codons three bases long, insertions and deletions can alter a gene so that its message is no longer correctly parsed. These changes are called frameshifts.
Detailed explanation-5: -A frameshift mutation in a gene refers to the insertion or deletion of nucleotide bases in numbers that are not multiples of three.
