Genes are portions of the DNA that provide information to makeproteins. Proteins are long strings of (b).The production of proteins is a multi-step process. The first step istranscription. The portion of the DNA (the gene) provides information tofirst make a different macromolecule called (c).This macromolecule then moves then moves into the cytoplasm. where translation, or protein synthesis, takes place. There, it attractstransfer RNA, which reads by codons. A codon consists of three(d) . Each transfer RNA consists of a codon with an(e) attached. By this process a protein is produced
