| A | B |
| DNA | a nucleic acid that consists of a double helix, remains in the nucleus, and contains the instructions needed to build proteins |
| mRNA | a nucleic acid that transcribes the instructions found on DNA and carries these instructions to the ribosomes |
| tRNA | a nucleic acid that transports amino acids to the ribosomes |
| ribosomes | organelles that are involved in protein synthesis |
| codon | a series of three bases on mRNA that are a code for an amino acid |
| anticodon | a series of three bases that complement a codon found on mRNA |
| transcription | the process that occurs in the nucleus where mRNA makes a copy of the instructions found on DNA |
| translation | the process that takes place along the ribosomes where the instructions found on mRNA are used to link amino acids together |
