| Term | Definition |
| Watson and Crick | American biologist/British physicist mad model o DNA double helix |
| DNA | long molecule shaped like a double helix mad of units called nucleotide |
| 3 components of nucleotide | 5 carbon sugar called deoxyribose, phosphate group, nitrogenous base |
| DNA backbone chain formed by | sugar and phosphate groups of each nucleotide |
| DNA joined by | hydrogen bond |
| 4 Nitrogenous Bases of DNA | adenine(A), thymine (T), Cytosine (C), Guanine (G) |
| purines (2 rings) | Adenine and Guanine |
| Pyrimidines (one ring) | thymine and cytosine |
| chargaff's Rule | percentages of guanine and cytosine almost equal in ANY dna sample (aka complementary base pairing) |
| Prokaryotic DNA | single celss that don't have genetic info contained in the nucleus but it is free floating in the cytoplasm |
| Eukaryotic DNA | DNA is in the nucleus in the form of a number of chromosomes |
| Chromosome structure | 1 meeter of DNA in human cell/ Eukaryotic DNA has both DNA and protein/ forms beadlike structure called nucleosome |
| DNA Replication | DNA is unzipped forming 2 strands, each original strand becomes a template |
| prokaryotic DNA replication | starts at 1 point, then goes in 2 directions until chromosome is duplicated at the replication fork (place where separation and replication occur) |
