- a One of a ribosome's three binding sites for tRNA during translation. The place where discharged tRNAs leave the ribosome.
- b One of a ribosome's three binding sites for tRNA during translation. Holds the tRNA carrying the growing polypeptide chain. (P stands for peptidyl tRNA
- c A specific nucleotide sequence in DNA that binds RNA polymerase and indicates where to start transcribing RNA
- d In prokaryotes, a special sequence of nucleotides in DNA that marks the end of a gene. It signals RNA polymerase to release the newly made RNA molecule, which then departs from the gene.
- e The premise that a gene is a segment of DNA that codes for one polypeptide.
