Q

What is the nucleoid region?

A

Area of the cell containing free floating, continuous, circular DNA thread

18
Q

Where is the area of the cell containing free floating, continuous, circular DNA thread ?

A

nucleoid region

19
Q

How do prokaryote cells divide?

A

binary fission

20
Q

What happens during binary fission?

A

DNA is copied, two daughter chromosomes attach to different parts of plasma membrane, then the cell divides. Division occurs through cell elongation and a protein called FtsZ that partitions new DNA
