MULTIPLE CHOICE QUESTION

1 min • 1 pt

DNA molecule segment is : TTA CGC AAG
The mutated DNA segment is TTC GCA AG. This is an example of ___ mutation.

Missense Substitution

Deletion Frameshift

Insertion Frameshift

Translocation Substitution

Answer explanation

The given DNA segment has a deletion mutation causing a frameshift, leading to a change in the reading frame. This matches the Deletion Frameshift mutation.

What mutation has occurred here? 
T-G-A-C-C-A
T-G-A-G-C-A

Substitution

Deletion

Insertion

Frameshift 

Answer explanation

The mutation is a substitution because a single nucleotide base (G) has been replaced by another (A) in the sequence.

GAG-CTC-GAC-AGA
Mutant
GAG CTC-CAC-AGA

Missense Substitution

Silent Substitution

Nonsense Substitution

Frameshift

Answer explanation

The mutation results in a single nucleotide change, causing a different amino acid to be incorporated. This is characteristic of a missense substitution.

Normal-
AGA-TTC-ATA-GCG
Mutant-
AGA-TTC-AAT-AGC-G

deletion frameshift

insertion frameshift

Missense substitution

nonsense substitution

Answer explanation

The correct answer is insertion frameshift because the mutation results in the insertion of an extra 'A' nucleotide, shifting the reading frame and changing subsequent amino acids.

DNA molecule segment is : TTA CGC AAG
The mutated DNA segment is TTA CGC AAA. This is an example of ___ mutation.

Silent Substitution

Insertion Frameshift

Missense Substitution

Nonsense Substitution

Answer explanation

The given DNA segment has a single nucleotide change that does not alter the amino acid sequence, making it a Silent Substitution mutation.

DNA molecule segment is : TTA CGC AAG
The mutated DNA segment is TTC GCA AG. This is an example of ___ mutation.

Missense Substitution

Deletion Frameshift

Insertion Frameshift

Nonsense Substitution

Answer explanation

The mutated DNA segment has an extra base (C) compared to the original, causing a frameshift mutation, specifically a Deletion Frameshift.

What type of chromosomal mutation is this?

Translocation

Inversion

Deletion

Duplication

Answer explanation

This is an example of an inversion chromosomal mutation where a segment of the chromosome is reversed. Inversions can lead to changes in gene expression and potential genetic disorders.
