Question

Choose the correct answers from the alternatives given :
The phenmomenon known as wobble refers to

• A. the movement of multiple ribosomes along the same mRNA
• B. the shifting of the reading frame in a deletion or insertion mutation
• C. the ability of a tRNA to pair with different codons that may differ in the third base
• D. the movement of a tRNA from the A to the P site

Answer 1

The correct option is C the ability of a tRNA to pair with different codons that may differ in the third base

According to wobble phenomenon or hypothesis, flexible base pairing at the third position of the codon-anticodon duplex is possible. This means a chance in the third nitrogenous base of a codon doesn't produce a different but same amino acid. Wobble phenomenon or hypothesis, thus, corresponds to the ability of a tRNA to pair with different codons that may differ in the third base. The amino acid also doesn't change.

So, the correct option is 'the ability of a tRNA to pair with different codons that may differ in the third base.'
