Question

Select correct statements regarding mutation. A. A point mutation involves substitution of a single nucleotide pair.
B. Frameshift mutations result from insertion or deletion of nucleotides not in multiples of 3.
C. Silent mutations always alter the amino acid sequence of a protein.
D. Mutagens can be physical, chemical or biological agents.
E. Auxotrophs can be easily grown on minimal media.
Choose the correct answer from the options given below :

• A. \(A, B \text{ and } D\) only
• B. \(A, B, E\) only
• C. \(C, D\) only
• D. \(A, C, E\) only

Hint:

Remember:
• Point mutation \(\rightarrow\) Single base substitution
• Frameshift mutation \(\rightarrow\) Insertion/deletion not multiple of 3
• Silent mutation \(\rightarrow\) No amino acid change \[ \text{Auxotrophs require supplemented media for growth} \]

Answer 1

The Correct Option is A
