What is segregation
|
the partitioning of chromosomes into daughter cells

|
|
With ____ DNa we see the rolling cirlce model of DNA replication
|
plasmid
|
|
|
what is a plasmid
|
1)it is smaller than a chromosome
2)DNA 3)Autonomus replication |
|
|
what is autonomus replication
|
plasmid replication is independent of the controls over chromosome replication
