| DNA Replication | A process in which DNA in the chromosomes is copied |
| Nitrogen Base | a carbon ring structure that contains one or more atoms of nitrogen |
| Messenger RNA | it brings information from the DNA in the nucleus to the cytoplasm |
| Transcription | in this process in the nucleus, enzymes make an RNA copy of a portion of a DNA strand |
| Translation | the process of converting th information in a sequence of nitrogen bases in mRNA into a sequence of amino acids that make up a protein |
| Frameshift Mutation | a mutation in which a single base is added or deleted from DNA |
| Chromosomal Mutation | when chromosomes break and rejoin backwards or join the wrong chromosome |
| Double Helix | the twisted together two strands of DNA-Looks like a long, twisted zipper |
| Codon | a set of 3 nitrogen bases in mRNA used to code amino acids |
| Ribosomal RNA | ribosomes from this attach onto mRNA and use its information to assemble amino acids |
| Transfer RNA | transports amino acids to the ribosome to be assembled in a protein |
| Mutation | a change in a single base pair in DNA |
| Mutagen | any agent that can cause a change in DNA |
| Point Mutation | a change in the DNA sequence that also changes the protein it codes for |
