Detailed explanation-1: -tRNA-transfer RNA is a small RNA that has a very specific secondary and tertiary structure such that it can bind an amino acid at one end, and mRNA at the other end. It acts as an adaptor to carry the amino acid elements of a protein to the appropriate place as coded for by the mRNA.
Detailed explanation-2: -Transfer RNA (tRNA) 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-3: -transfer RNA (tRNA), small molecule in cells that carries amino acids to organelles called ribosomes, where they are linked into proteins.
Detailed explanation-4: -Amino acids are attached to tRNAs at the 3′-terminal adenosine at the end of a CCA trinucleotide sequence that is common to all tRNAs. In the second domain is a trinucleotide sequence known as the anticodon, located ∼75 Å from the amino acid attachment site.
