| A | B |
| Ribonucleic Acid | RNA- a temporary copy of DNA |
| Uracil | A nucleotide base found only in RNA, it pairs with adenine |
| Messenger RNA | RNA that is a temporary copy of a gene that contains instructions for making a protein |
| Transfer RNA | RNA that carries amino acids to where a protein is being made |
| Ribosomal RNA | RNA found inside the ribosome |
| RNA polymerase | An enzyme that matches nucleic acid basepairs during transcription |
| Transcription | The process of making DNA into mRNA; it is the first step of protein synthesis |
| Amino acid | A building block of protein |
| Translation | The process of making a protein from mRNA, the second step of protein synthesis |
| Codon | Three consecutive bases on mRNA |
| Anti-codon | The complementary bases of a codon, found in tRNA |
| Start codon | AUG |
| Stop codon | A codon that has no amino acid matching it, it stops protein synthesis. |
