| Nucleotide | Monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogen base |
| mRNA | Carries copies of genes from the nucleus to the cytoplasm |
| rRNA | Type of RNA found in ribosomes |
| RNA | Single-stranded nucleic acid that contains the sugar ribose |
| tRNA | Type of RNA molecule that transfers amino acids to ribosomes during protein synthesis |
| Transcription | Process in which part of DNA is copied into a complementary sequence in RNA |
| RNA Polymerase | Enzyme that binds to DNA and separates the DNA strands during transcription |
| Intron | Part of DNA sequence that is removed during editing |
| Exon | Part of DNA sequence that is NOT removed during editing |
| Codon | Three-nucleotide sequence on messenger RNA that codes for a single amino acid |
| Uracil | Nucleotide that replaces "thymine" in RNA |
| Ribose | Sugar that replaces "deoxyribose" in RNA |
| Thymine | Nucleotide that is replaced by "uracil" in RNA |
| Nucleus | Cell organelle where mRNA is synthesized |
| Cytoplasm | Part of the cell where mRNA exits to |
