| Adenine | one of the bases which make up the genetic code of DNA and RNA |
| Thymine | a pyrimidine base that is one of the bases coding hereditary information in DNA |
| Cytosine | a chemical base that is pyrimidine and codes genetic information in DNA and RNA |
| Guanine | a purine base that code genetic information in DNA and RNA |
| Genetic | caused or controlled by genes |
| Genealogy | the study of family lines of ancestors |
| DNA | any of various nucleic acids that are located especially in cell nuclei, are usually the chemical basis of heredity, and are composed of two nucleotide chains held together by hydrogen bonds in a pattern resembling a flexible twisted ladder |
| RNA | any of various nucleic acids that are typically found in the cytoplasm of cells, are usually composed of a single chain of nucleotides, differ from DNA in containing ribose as the five-carbon sugar instead of deoxyribose, and that function mostly in protein synthesis |
| Heritable | capable of being inherited |
| bacteria | simple, one cell and organism that lack a nucleus |
| cell division | the process that result in two cells being formed from one cell |
| codon | a code word of messenger RNA that represent an acid |
| Double Helix | the double spiral shape of the DNA molecule |
| Molecule | a combination of two or more atoms bonded together by strong chemical bonds |
