Document Summary
Phylogenetically anomalous resemble fungi, moss, or even dog barf . Folding 3200 mb of dna into nucleus. Cells arise by division of pre-existing cells. Two types of cell division: mitosis, meiosis. Division of genetic material to produce 2 daughter cells identical to parent cell. Usually accompanied by cytokinesis division of cytoplasm into two daughter cells. Involved only in the production of somatic (body) cells. Responsible for 3 key events in eukaryotes: growth, wound repair, cellular reproduction. Division of genetic material to produce daughter cells with of hereditary material found in parent cell. Involved only in the production of gametes (eggs and sperm) Basis of sexual reproduction and genetic inheritance. Contain a long double helix of dna wrapped around histone proteins. Chromosomes can be stained with dyes and observed under light microscopes. Two sister chromatids separate to form independent chromosomes one copy of each chromosome goes to each daughter cell.
