The acceptor stem is the site of attachment of amino acids to transfer RNA (tRNA). It is formed by 7 base pairs and has 4 single-stranded nucleotides.

Does tRNA have a 5 acceptor stem?

The tRNA structure consists of the following: A 5′-terminal phosphate group. The acceptor stem is a 7- to 9-base pair (bp) stem made by the base pairing of the 5′-terminal nucleotide with the 3′-terminal nucleotide (which contains the CCA 3′-terminal group used to attach the amino acid).

What is the role of the acceptor arm of the tRNA molecule?

Question: What is the role of the acceptor arm of the tRNA molecule? binding a specific amino acid binding to the growing polypeptide chain binding to the codon sequence in the DNA binding to the ribosome .
