Question

Select the incorrect statement about tRNA.

• A. tRNA possess an amino acid acceptor at 3' end for binding of amino acids.
• B. tRNA is also called soluble RNA.
• C. Only single tRNA exists for all 3 stop codons.
• D. tRNA possess an anticodon loop that has bases complementary to the code.

Answer 1

Answer: (C)

tRNA has anticodon loop which has anticodons complementary to the codons of mRNA. Due to very small size tRNA is also called as soluble RNA. Amino acid binds to 3' end of tRNA. Three stop codons does not have any anticodons thus no tRNA is there for stop codons.
