Answer: linear or circular. include genes encoding viral proteins: capsid, envelope proteins, any polymerase not found in the host cell. viruses may have a lipid envelope.
Answer: 1. Cyclin-dependent kinases.

3. They are activated when cdks sends signals to cell that is pass already into the next stage of the cell cycle.
4. They are inactivated by the combination of P21 and Thr-14/Tyr-15 phosphorylation after uv induced DNA damage.
5. Changes are seen in target protein level when cdks level rises.
6. The targets are protein that promotes cell divisions.
