Protein Synthesis
Term | Definition |
---|---|
Ribonucleic Acid | RNA; A natural polymer that is present in a ll 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 DNA molecule as a template |
Translation | The portion of protein synthesis that takes place at ribosomes |
Protein Synthesis | The formation of proteins by using information contained in DNA and carried by mRNA |
Ribose | A five-carbon sugar present in RNA |
Messenger RNA (mRNA) | A single-stranded RNA molecule that encodes the information to make a protein |
Ribosomal RNA (rRNA) | An organelle that contains most of the RNA in the cell and that is responsible for ribosome function |
Transfer RNA (tRNA) | an RNA molecule that transfers amino acids to the growing end of a polypeptide chain during translation |
RNA Polymerase | An enzyme that starts (catalyzes) the formation 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 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 complementary to the codon of mRNA |
Genome | The complete genetic material contained in an individual |
