The correct answer is: identifies amino acids and transports them to ribosomes
The tRNA molecules are the smallest, made up of 75 to 80 nucleotides. The transfer RNA recognizes the codons of mRNA and exhibit high affinity for 21 activated amino acids, combine with them and carry them to the site of protein synthesis. The 3I end of the polynucleotide chain ends in the CCA base sequence, the site for the attachment of activated amino acid.
