Detailed explanation-1: -An example of point mutation is sickle cell anaemia. It involves mutation in a single base pair in the beta-globin chain of haemoglobin pigment of the blood.
Detailed explanation-2: -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-3: -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.
Detailed explanation-4: -Hereditary mutations include cystic fibrosis, hemophilia, and sickle cell disease. Other mutations can happen on their own during a person’s life. These are called sporadic, spontaneous, or new mutations. They affect only some cells.
