It bonds to other RNA molecules, leading to their destruction.
|

It carries the information coding for the amino acid sequence of a protein.

Detailed explanation-1: -Transfer RNA (abbreviated tRNA) is a small RNA molecule that plays a key role in protein synthesis. Transfer RNA serves as a link (or adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a protein.
Detailed explanation-2: -tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges, ” matching a codon in an mRNA with the amino acid it codes for.
Detailed explanation-3: -Transfer RNA (tRNA) brings the correct amino acids to the ribosome and adds them to the polypeptide chain.
Detailed explanation-4: -Transfer RNAs (tRNAs) are adaptor molecules that translate genetic information into protein sequence by delivering amino acids to the protein synthesis machinery during translation.
Detailed explanation-5: -The tRNA that has given up its amino acid is released. It can then bind to another molecule of the amino acid and be used again later in the protein-making process. Using a ratcheting mechanism, the ribosome advances the mRNA, three nucleotides at a time.
