Question

Which of the following statements is correct ? A. Intercalating agents distort DNA to induce single nucleotide pair insertions and deletions.
B. T and G typically exist in the amino form and A and C in the keto form.
C. Base analogues are structurally similar to normal nitrogenous bases.
D. Point mutations are mutations that occur at specific positions.
E. Nonsense mutations convert a sense codon to a stop codon.
Choose the correct answer from the options given below :

• A. \(A, B\) only
• B. \(B, D\) only
• C. \(A, C, E\) only
• D. \(C, D\) only

Hint:

Remember:
• Intercalating agents \(\rightarrow\) Frameshift mutations
• Base analogues \(\rightarrow\) Resemble normal bases
• Nonsense mutation \(\rightarrow\) Produces stop codon Normal tautomeric forms: \[ A,C \rightarrow \text{Amino} \] \[ G,T \rightarrow \text{Keto} \]

Answer 1

The Correct Option is C
