| Chromosome | made of linear DNA which contains genetic info in the form of genes. coiled around histone proteins. |
| Gene | sections od DNA that codes for protein |
| Where do new cells come from | Mitosis and meiosis of existing cells. |
| centromere | thing that binds different ends of chromatids together |
| chromatin | Decondensed chromosomes (chromosomes that are not going through cell devision |
| what are chromosomes made of | 70% highly basic (alkaline) proteins and histone proteins
15% DNA (Deoxyribonucleic acid)
we don't know the other bits |
| DNA | Deoxyribonucleic acid, inherited, made up of genes |
| What are the two phases of cell division | Nuclear division and Cytokenesis |
| What is nuclear division | 1st phase of mitotic cell division
nucleus divides
DNA synthesis occurs |
| Cytokenesis | 2nd phase of mitotic cell division
cytoplasm and organelles are shared between cells |
| what are all the phases of the cell cycle | Mitosis, growth1, synthesis, growth2, interphase |
| What happens during both growth phases | G1 Proteins mode, organell replicate, biochemical produce
G2 Organelles replicate, microtubules form, more mitochondria produced |
