Detailed explanation-1: -Mutations are changes that occur in DNA or RNA. Mutations can be silent, meaning they have no effect on the protein made, due to redundancy in the genetic code.
Detailed explanation-2: -(deh-LEE-shun) A type of genetic change that involves the absence of a segment of DNA. It may be as small as a single base but can vary significantly in size.
Detailed explanation-3: -Instead, a deletion mutation will usually occur in the middle of a chromosome or gene. This will cause the deleted nucleotide to be filled by shifting the DNA and causing a frameshift mutation, or inserting a new nucleotide in a mutation known as an insertion.
Detailed explanation-4: -A frameshift mutation in a gene refers to the insertion or deletion of nucleotide bases in numbers that are not multiples of three.
