3Ribosome — The cell s essential protein factory. A tiny particulate structure located in the cytoplasm of the cell (outside the nucleus), the ribosome is composed of two subunits, one larger than the other. Both subunits were believed to contain both RNA… …
4aminoacyl site — (acceptor site or A site) The site on the ribosome that contains an aminoacyl tRNA at the beginning of the elongation cycle during protein synthesis; the growing peptide chain is transferred to the aminoacyl tRNA and lengthens by an amino acid …
5ribosome — A heterodimeric multi subunit enzyme composed of ribonucleoprotein and protein subunits. Interacts with aminoacylated tRNAs, and mRNAs and translates protein coding sequences from messenger RNA. During protein elongation, the nascent protein is… …
6A-site — Site on the ribosome to which aminoacyl tRNA attaches during the process of peptide synthesis. See also P site …
7P-site — The P site (for peptidyl) is the second binding site for t RNA in the ribosome. The other two sites are the A site (aminoacyl), which is the first binding site in the ribosome, and the E site (exit), which is the third and final binding site in… …
8P-site — The peptidyl tRNA binding site on the ribosome, the one to which the growing chain is attached; the incoming aminoacyl tRNA attaches to the A site …
9metabolism — /meuh tab euh liz euhm/, n. 1. Biol., Physiol. the sum of the physical and chemical processes in an organism by which its material substance is produced, maintained, and destroyed, and by which energy is made available. Cf. anabolism, catabolism …
