Detailed explanation-1: -The tRNA is located in the ribosome’s first docking site. This tRNA’s anticodon is complementary to the mRNA’s initiation codon, where translation starts. The tRNA carries the amino acid that corresponds to that codon.

Detailed explanation-2: -One end of the tRNA binds to a specific amino acid (amino acid attachment site) and the other end has an anticodon that will bind to an mRNA codon. One end of the L shape has the anticodon, while the other has the attachment site for the amino acid.

Detailed explanation-3: -Anticodon An anticodon is a trinucleotide sequence located at one end of a transfer RNA (tRNA) molecule, which is complementary to a corresponding codon in a messenger RNA (mRNA) sequence.

Detailed explanation-4: -At the 3’ end of the tRNA molecule, opposite the anticodon, extends a three nucleotide acceptor site that includes a free-OH group. A specific tRNA binds to a specific amino acid through its acceptor stem. The cloverleaf structure shown above is actually a two dimensional simplification of the actual tRNA structure.

Detailed explanation-5: -A tRNA molecule will enter the ribosome bound to an amino acid. The anticodon sequence will bind to the codon of the mRNA, allowing the tRNA to release the attached amino acid.
