Question
DNA molecule segment is: TTACGCAAG
The mutated DNA segment is TTCGCAAG. This is an example of ___ mutation.
- Substitution
- Deletion
- Insertion
- Inversion
Hint:
In the sequence TTACGCAAG, the A nucleotide is removed and mutated to TTCGCAAG. It is a deletion mutation.
The correct answer is: Deletion
- 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.
- In the sequence TTACGCAAG, the A nucleotide is removed and mutated to TTCGCAAG.
