Document Summary
8. 1 the cell cycle of growth and division. Chapter 8 cell cycles: cells divide too fast, daughter cell can end up with less cytoplasm and dna, cells divide too slow, daughter cell can end up with an extra chromosome, or be inefficiently large. 8. 2a replication occupies most of the cell cycle in rapidly dividing prokaryotes. Binary fission: the entire cell division mechanism in prokaryotes. All genetic material in prokaryotes are packaged into one single circular chromosome, found in a compact area called a nucleoid. If nutrients in abundant than the cell cycle occurs rapidly along with growth. 8. 2b replicated chromosome are distributed actively to the hales of the prokaryotic cell. Two replicated origins migrate to the poles of the cell while replication continues. Origin of replication: area in prokaryotes where replication enzymes are found and once the ori gets duplicated it move to opposite ends. 8. 3a chromosomes are the genetic units divided by mitosis.
