Detailed explanation-1: -A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand (Figure 3). Figure 3: In a deletion mutation, a wrinkle forms on the DNA template strand, which causes a nucleotide to be omitted from the replicated strand.

Detailed explanation-2: -Cystic fibrosis is brought about by a point deletion in the CFTR gene, leading to abnormal production of the CFTR protein. Another example of a deletion mutation-related disorder is Turner syndrome, where there is a deletion of the entirety of the X chromosome.

Detailed explanation-3: -Definition. A point mutation occurs in a genome when a single base pair is added, deleted or changed. While most point mutations are benign, they can also have various functional consequences, including changes in gene expression or alterations in encoded proteins.
