Term | Definition |
Ribonucleic acid | a natural polymer that is present in all living cells and that plays a role in protein synthesis |
transcription | the process of forming a nucleic acid by using another molecule as a template; particularly the process of synthesizing RNA by using one strand of a DNA molecule as a template |
translation | the portion of protein synthesis that takes place at ribosomes and that uses the codons in mRNA molecules to specify the sequence of amino acids in polupeptide chains |
protein synthesis | the formation of proteins by using info contained in DNA and carried by mRNA |
ribose | a five carbon sugar present in RNA |
messenger RNA | a single stranded RNA molecule that encodes the info to make a protein |
ribosomal RNA | an organelle that contains most of the RNA in the cell that is responsible for ribosome function |
transfer RNA | an RNA molecule that transfers amino acids to the growing end of a polypeptide chain during translation |
RNA polymerase | an enzyme that starts the formation of RNA by using of strand of a DNA molecule as a template |
promoter | a nucleotide sequence on a DNA molecule to which an RNA polymerase molecule binds, which initiates the transcription of a specific gene |
termination signal | a specific sequence of nucleotides that marks the end of a gene |
genetic code | the rule that describes how a sequence of nucleotides, read in groups of three consecutive nucleotides (triplets) that correspond to specific amino acids, specifies the amino acid sequence of a protein |
codon | in DNA a three nucleotide sequence that encodes an amino acid or signifies a start signal or a stop signal |
anticodon | a region of tRNA that consists of three bases complimentary to the codon of mRNA |
