Detailed explanation-1: -Types of Point Mutations. We are going to focus on the following point mutations: frameshift, silent, nonsense, and missense. Let’s start with a frameshift mutation, where there’s an insertion or deletion of one or more bases.
Detailed explanation-2: -Which of the following is not a point mutation? Explanation: Point mutation concerns a single base. Thus substitution, which includes transversion, and insertion or deletion, falls within point mutation. On the other hand, translocation involves a stretch of bases so it is not a point mutation.
Detailed explanation-3: -These groupings are divided into silent mutations, missense mutations, and nonsense mutations.
Detailed explanation-4: -There are three types of point mutations: deletions, insertions, and substitutions. Deletions occur when a nucleotide is deleted. Insertions happen when a new nucleotide is inserted into the genome. Substitutions happen when a nucleotide is swapped for another nucleotide.
