| DNA | type of molecule that decides our traits |
| James Watson and Francis Crick | discovered that DNA resembles a long twisted up ladder |
| Difference between RNA and DNA | one has a differnt sugar in its backbone |
| replication | one strand splitting apart forming two strands would show what? |
| mutations cause | diseases such as sickle-cell anemia or down syndrom |
| inherited genetic disorders | explains a change in DNA rhat causes a disease that was passed from parent to offspring |
| two ways mutations occur | randomw errors during replication or damage by mutagens |
| Isolated DNA | when scientists identify the nucleotide bases - adenine, cystonine, guanine, and thymine what are tey doing? |
| both of these makes up 40% in a base pair | thymine and adenine |
| ribosome | organelle made of RNA and protein |
| RNA | forms when DNA is copied into a seperate molecule |
| mutations | number, type, or order changes that occur on DNA pieces |
| deletion | changes occuring to DNA that leaves a base out |
| insertion | DNA changes that add an extra base |
| substitution | common mutation that has a base replace another base |
| replication | cells that can make copies of DNA molecules through this process |
| nucleotide | building block of DNA consisting of phosphate, sugar, and a base |
| DNA looks like | a double helix |
| DNA | refers to all genetic material in cells |
| replication happens when? | before cells divide |
