gene Unit of heredity containing the instructions that dictate the characteristics or phenotype of an organism; in molecular terms, a segment of DNA that directs the production of a particular protein or functional RNA molecule. transription Process in which RNA polymerase uses one strand of DNA as a template to synthesize a complementary RNA sequence. RNA Molecule produced by the transcription of DNA; usually single-stranded, it is a polynucleotide composed of covalently linked ribonucleotide...
