Question

The following image shows the mechanism of _______ mutation.

  1. Point mutation.

  2. Inversion mutation.

  3. Deletion mutation.

  4. None of the above.

Hint:

We can see a part of a chromosome is getting removed.

The correct answer is:

Deletion mutation.


    • Deletions alter the DNA sequence by removing at least one nucleotide within the gene. Small deletions remove one or a few nucleotides within a gene, whereas large deletions may remove the entire gene or several adjacent genes.
    • Deleted DNA may alter the function of the affected protein. It causes cystic fibrosis, Turner syndrome, and Williams syndrome.
