Document Summary

The daughter cells need the complete genetic complement: the genetic material of prokaryotes is?circular dna. Prokaryotes: circular strands of dna, replicate dna and pass it on to daughter cell, divide by binary fission. Eukaryotes: genetic material is found in linear chromosomes. Mitosis: how many centromeres per chromosome?1, how many centromeres per chromosome consisting of 2 sister chromatids?1. Interphase: generally 90% of cell cycle, gap 1 (g1)-increase in number of organelles, s phase-dna is duplicated, gap 2 (g2)- centrioles replicate in animal cells, mitotic phase, mitosis, cytokinesis, what does a centriole resemble?the base of a flagellum. In animals: found in centrosome, 9 sets of triplet microtubules arrange in a ring, the purpose of mitosis is so the daughter cells are identical to the mother, dna is replicated? Mitosis- the cell division in eukaryotes to produce daughter cells which have identical genetic material to the mother cell.
