5′ cap - A modified form of guanine nucleotide added onto the 5′ end of a pre-mRNA molecule. A site - One of a ribosome's three binding sites for tRNA during translation. The A site holds the tRNA carrying the next amino acid to be added to the polypeptide chain. (A stands for aminoacyl tRNA.) ABC hypothesis - A model of flower formation identifying three classes of organ identity genes that direct formation of the four types of floral organs. abiotic - Nonliving; referring to th...
