|---|---|
| Gene | DNA sequence that encodes an RNA or protein product |
| Gene expression | Process by which the information in a gene becomes converted to an RNA or protein product |
| Messenger RNA (mRNA) | A type of RNA that carries a protein-building message |
| Ribosomal RNA (rRNA) | A type of RNA that becomes part of ribosomes. |
| Transcription | Converts info in a gene to RNA |
| Transfer RNA (tRNA) | A type of RNA that delivers amino acids to a ribosome during translation |
| Translation | Converts info in an mRNA to protein |
| alternative splicing | RNA processing event where some exons are removed or join in alternative combinations |
| exon | Nucleotide sequence that is not spliced out of RNA during processing |
| Intron | Nucleotide sequence that intervenes between exons and is excised during RNA processing |
| Promoter | In DNA, a sequence to which RNA polymerase binds |
| RNA Polymerase | Enzyme that carries out transcription |
| anticodon | set of 3 nucleotides in tRNA; base pairs w/ mRNA codon |
| codon | In mRNA, a nucleotide base triplet that codes for an amino acid or stop signal during translation |
| Genetic code | complete set of 64 mRNA codons |
