| Adenine pairs with | Thymine |
| Cytosine | pairs with guanine |
| polymer | large molecule made from bonding monomers |
| Nucleotides | monomer of DNA |
| Transcription | production of m-RNA using a DNA template |
| m-RNA structure | straight chain of nucleotides |
| Uracil | replaces thymine in m-RNA |

| codon | every 3 m-RNA bases that codes for one amino acid |
| t-RNA | transfer RNA; brings amino acid to ribosome |
| gene | series of DNA bases that codes for one protein |
| mutation | change in genetic information |
| protein | polymer made from monomers |
| amino acids | monomers of proteins |
| AUG | start codon |
| stop codons | found on m-RNA to stop protein production |
| base pairing rule | A-T and C-G for DNA |
| One DNA strand | used to make a m-RNA |
| anticodon | A nucleotide triplet at one end of a tRNA molecule that recognizes a particular complementary codon on an mRNA molecule. |
| codon | A three-nucleotide sequence of DNA or mRNA that specifies a particular amino acid or termination signal; the basic unit of the genetic code. |
| exon | A sequence within a primary transcript that remains in the RNA after RNA processing |
| intron | A noncoding, intervening sequence within a primary transcript that is removed from the transcript during RNA processing |
