Story so far…cell is the fundamental unit oflifeLiving cells possess a system that stores theinstructions required to make the components(biomacromolecules) necessary to sustainlife…this information is stored in such a way thatit can be passed on in it’s entirety to its progeny,so that they may sustain life.Eukaryotic cellProkaryotic cellDNA(no nucleus)DNA (throughoutnucleus)

What about prokaryotes?
Why do cells divide?Reproduce the organism (prokaryotes).If the organism is eukaryote,cellsdivide to reproduce organism(unicellular yeasts), replace dead cellsor to allow the organism to grow.s/BI0032/repro/malecon.htmphotos/5264093772/in/photostream/Celldivision:Total DNAReplicationInformationTransfer
Cell division in either prokaryotes or eukaryotesmust be accompanied by replication of DNA
