Document Summary

Lecture 26: dna - the stuff of heredity. Prokaryotes dna replication: undergo binary fission, bacteria grows and creates proteins. After it gets big enough, it starts replicating at origin. Dna polymerase runs through the cell: the cell is split with the origin in each of the cells, results in two identical bacteria cells, add from lecture** Some bacteria have plasmids (circular dna: the dna with f plasmid is calle f plus. The oenwithout is called f minus: dna poly extends from 5 to 3 restroing the plasmid. In the new cell, the single stranded dna is replicated in pieces. The solenod fibers are looped around the scaffold. Further shortened and thicker, and ready to be used in interphase. The gens on this chromosome swill not be turned on, and will not undergo transcription. Anatomy of the chrosome: there are two long pieces of dna which are identical to each other.
