DNA Translation Polypeptide chain - A chain of many peptide, or amino acid, subunits joined together through peptide bonds. Polyribosome - Term used to describe a group of separate ribosomes that are bound to the same mRNA strand. Pseudouridine - One of the unusual bases found in tRNA in which the normal 1' nitrogen site of ribose attachment is switched to the 5' carbon position. Release factor - A protein that recognizes one of three stop codons on an mRNA chain. Its binding results in the release of the completed polypeptide chain and the dissociation of the 30S and 50S subunits. Ribosome - The structure in the cell, made up of protein and RNA (rRNA), that functions as the "factory" of protein synthesis. Ribosomes contain a binding site for mRNA, and three

Unformatted text preview: binding sites for tRNA: the acceptor site, the peptidyl site, and the exit site. Ribosome binding site - An approximately 10 nucleotide sequence found in a prokaryotic mRNA strand that is recognized and bound by the ribosome. Located 5 to 11 nucleotides from the initiator codon. In eukaryotes, the ribosome binding site is functionally replaced by the 5' cap. T arm - A secondary structural feature of tRNA. Contains the sequence thymine- pseudouridine-cytosine in its stem loop. Translocation - The process in which the ribosome moves three nucleotides down an mRNA strand in the 3' direction. Process is catalyzed by the hydrolysis of GTP to GDP....
