| DNA | an acronym for Deoxyribonucleic Acid |
| Nucleus | where DNA is stored in a cell |
| Double Helix | the shape of DNA |
| Adenine | one of four bases in DNA, represented by an "A" |
| Guanine | one of four bases in DNA, represented by a "G" |
| Cytosine | one of four bases in DNA, represented by a "C" |
| Thymine | one of four bases in DNA, represented by a "T" |
| Chargaff | the scientist that discovered the amount of A=T and C=G |
| Franklin | using x-ray diffraction, she discovered that DNA is a helix shape |
| Watson and Crick | two scientists who created the first working model of DNA |
| antiparallel | the two sides of DNA run in opposite dirrections |
| nucleotide | 1 sugar, 1 phosphate, and 1 base |
| hydrogen bonds | the type of bonds that connect bases in DNA |
| base pairs | adenine always bonds with thymine and cytosine always bonds with guanine |
| genes | a sequence of DNA that codes for a protein |
| chromosome | a mixture of DNA and proteins wound together and condensed to form a rod-like structure |
| Two bonds | form between Adenine and Thymine |
| Three bonds | form between Cytosine and Guanine |
