DNA gets compact only during cell division and are called chromosomes. On other conditons, it forms a network of thin threads called chromatin network.
Answer:
C. glycosylation
Explanation:
The maturation-promoting factor (MPF) is a cell cycle checkpoint that stimulates the passage from G2 (prophase) to M phase (metaphase). MPF also determines that DNA replication during the S (synthesis) phase did not produce any mutations. MPF is inactivated by kinase phosphorylation and activated by specific phosphatases capable of dephosphorylating this protein. On the other hand, glycosylation is a posttranslational modification where a carbohydrate (i.e., a glycan) is added to a functional group of another molecule. Many proteins undergo glycosylation, thereby playing a critical role in regulating protein function.
I'm pretty sure the answer is C, there are 4 nitrogenous bases involved.

They are not able to reproduce independently
They do not use energy for metabolism of any kind
<span>Their virulence is maintained by non-living cultures

They are much like empty rooms false
the cell lacks a nucleus is true
the rest are wrong
