Document Summary
Cells need to possess the genetic material characteristics of the organism. The daughter cells need the complete genetic compliment. Replicate the dna & pass it on to the daughter cells. Linear strand of dna complexed w/ proteins. You need a copy of each of the chromosomes. The solution : mitosis - produces daughter cells with the 2n chromosome number; diploid (2n) Produce daughter cells that have identical genetic compliments. Occurs in somatic cells (not involved in sexual reproduction) Each eukary species has a characteristic # Attached at a specialized region consisting of dna & proteins called the. 1 centromere per chromosome of sister chromatids. Synthesis (replication) of the genetic material (material doubles) 9 sets of triplet microtubules arranges in a ring. Found in the centrosome (a region from which microtubules grow out) Help organize microtubule growth (but centrioles are not necessary, most plants lack centrioles) * as centrosomes move away from each other the microtubules lengthen.
