|
string together complementary RNA and DNA strands

|
bring amino acids from the cytoplasm to the ribosomes
|
Detailed explanation-1: -Transfer RNAs or tRNAs are molecules that act as carriers of amino acids, bringing the appropriate amino acids to the ribosome (protein synthesis site) based on the messenger RNA (mRNA) nucleotide sequence. Q. The function of tRNA is to transfer from the cytoplasm to the site of protein synthesis.
Detailed explanation-2: -Ribosomes provide a structure in which translation can take place. They also catalyze the reaction that links amino acids to make a new protein. 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: -Definition. 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-4: -Transfer RNA, abbreviated tRNA, brings amino acids to the ribosome. There are sixty-four possible formations of tRNA, and each tRNA is bonded to a specific amino acid. The ribosome matches the tRNA code to the mRNA code to build the correct sequence of amino acids.
