Document Summary
Cells need processes the genetic material characteristic of the organism. Replicate the dna and pass it on to the daughter cells. Genetic material is in linear chromosomes: linear strands of dna complexed. The solution to make sure both cells get identical genetic. Complex of a linear strand of dna and protein. 9 sets of triplet microtubules arranged in a ring. Found in the centrosome: a region where microtubules grow out. Help organize microtubules growth: centrioles are not necessary, most plants lack centrioles. Mitotic spindle forms from microtubules in cytoplasm. Microtubules of spindle invade with the chromosomes via the kinetochore. Structure of proteins and specific sections of chromosomal dna at the centromere. Formed from microtubule extending from the 2 centrosomes. Sister chromatids separate and move towards the pole. Actin microfilaments form a ring around the equator of the divining cell. Vesicles from golgi form a cell plate at the equator of the dividing cell.
