What is inosine,and what role does it play in translation?
A)Inosine is a purine base that,when in an anticodon opposite the third base of a codon,provides flexibility in base pairing.
B)Inosine is a sugar that,when metabolized near a ribosome,provides energy for the formation of peptide bonds.
C)Inosine is an enzyme that,when linked to the active site of a ribosome,catalyzes the process of translocation.
D)Inosine is a regulatory molecule that,when bound to a ribonuclease,controls the rate of degradation of mRNA.

Inosine is a purine base that is often found in tRNA molecules. When in an anticodon opposite the third base of a codon, it provides flexibility in base pairing. This allows for the recognition of more than one codon by a single tRNA molecule, reducing the number of tRNA molecules required in the cell.
