Question
The following image shows the mechanism of _______ mutation.

Point mutation.
Inversion mutation.
Deletion mutation.
None of the above.
Point mutation.
Inversion mutation.
Deletion mutation.
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.
