Q. Assertion: tRNA can recognize more than one codon differing at third position only. Reason: The codon is mainly specified by first two bases and third base represent wobble position.
A) Both assertion and reason are true and reason is the correct explanation of assertion.
B) Both assertion and reason are true but reason is not correct explanation of assertion.
C) Assertion is true, but reason is false.
D) Both assertion and reason are false
Explanation
The tRNA molecule can recognize more than one codons which differ at third position. The third nitrogenous base of a codon binds loosely with anti-codon and thus, the codon is specified mainly by first two bases.
