| A | B |
| Transcription | making RNA complementary to DNA |
| complementary | matching (fitting together) |
| DNA polymerase (DNA pol) | replicates DNA |
| RNA polymerase (RNA pol) | Transcribes DNA into RNA |
| Replication | DNA pol makes a copy of DNA |
| translation | mRNA translated into a protein |
| codon | 3 consecutive bases coding for an amino acid |
| anti-codon | 3 consecutive bases on tRNA |
| tRNA | transfer RNA brings amino acids to the ribosome |
| mRNA | messenger RNA sends the message to the ribosome (what protein to make) |
| ribosome | makes proteins |
| amino acid (aas) | aas form long chains to make proteins |
