3. Select all of the following statements that are true of tRNAs

A)64 different tRNAs are used in each organism

B)for a tRNA to function correctly, it's anticodon must bind correctly to both mRNA and to an aminoacyl tRNA synthetase.

C)most organisms do not use all of the available tRNAs; this differs between species

D)the nucleotides of a tRNA do not form hydrogen bonds

Solutions

Expert Solution

Transfer RNA or tRNA is the key to decode the codons of mRNA. Each amino acid has it's own subset of tRNAs.

An aminoacyle-tRNA synthase binds to the D-loop of the tRNA and couples a specific amino acid to the 3' hydroxyl of terminal adenosine of acceptor stem.

The 3-base sequence(anticodon) of the tRNA of anticodon loop then base pair with the corresponding codon in mRNA.

Ribosome incorporates the amino acid to the growing peptide chain and releases the tRNA.

Number of tRNA is more than the number of amino acids and it also differs from the number of genetic code. Many amino acids have more than one tRNA to which it can attach.

H-bonds present at the stems of the tRNA. It helps in formation and stability to the structure of tRNA.

True statement about tRNAs : c) Most organisms do not use all of the available tRNAs; this differ between species.

All other options are False.
