Question
Identify the DELETION mutation from the following:
ATG CCA AAT
- ATG TCA AAT
- ATG CCT AAA T
- ATC CA AT
- ATG CCA AAT
Hint:
Deletion mutations can cause abnormal protein synthesis leading to a range of medical disorders. For example, cystic fibrosis, Turner syndrome, and Williams syndrome.
The correct answer is: ATC CA AT
- A deletion changes the DNA sequence by removing at least one nucleotide in a gene. Small deletions remove one or a few nucleotides within a gene, while larger deletions can remove an entire gene or several neighboring genes.
- The deleted DNA may alter the function of the affected protein or proteins.
