Describe how the information on DNA is used to construct polypeptides, including the role of messenger RNA, tr?

RNA polymerase is an enzyme that makes a strand of (messenger) RNA from a template of a single strand of DNA. The nucleotides that make up the mRNA hook up with complementary transfer RNA, which has an amino acid on one end and a three-nucleotide sequence on the other. So multiple tRNAs line up next to each other as they attach to the complementary bases on the mRNA. This causes the corresponding amino acids to line up next to each other. They form bonds between each other, and a string of amino acids is a polypeptide. A protein is made of one or several polypeptides. Ribosomes are the organelles that perform the polypeptide synthesis.
