process in which RNA is synthesized from DNA a group of three nitrogenous bases in DNA or mRNA that code for one amino acid nucleic acid made of ribose, phosphate, and one of four nitrogenous bases--adenine, cytosine, guanine, or uracil intervening DNA sequences that are transcribed and then removed from the final mRNA process by which mRNA directs the synthesis of a protein long strands of RNA that are complementary to one strand of DNA protein coding sequences in DNA that are transcribed into mRNA and translated into protein small RNA molecules that transport amino acids to the ribosome an enzyme that catalyzes the synthesis of mRNA using a specific section of DNA as a template RNA molecules that make up part of the ribosome
