Answer:
Option B. Viral genes may be encoded by DNA or RNA, but cellular genes are always encoded by DNA.
Explanation:
Virus is a unique organism having unique characteristics which act as both living and non living. In cell, it is living while outside the cell it is present in crystalline form. Virus is composed of two genome i. e. DNA or RNA. But cell is composed of only DNA genome. There is no nucleus present in virus. Mitochondria and ribosome are also absent.
The clotting mechanism, chemicals released from damaged tissues trigger the cascade of events that ultimately result in the formation of hemostasis.
Hemostasis is reached by a series of actions known as the coagulation pathway or clotting mechanism. The complex system enables quick healing and stops uncontrolled bleeding. Fibrin activation is the result of the convergence at a certain site of two routes, intrinsic and extrinsic, which start off independently. The end goal is to use a fibrin mesh to stabilise the platelet plug.
The coagulation pathway's job is to maintain hemostasis, which is the cessation of bleeding or haemorrhaging. Primary hemostasis is the formation of a plug of platelets at the injured region where exposed endothelial cells are present.
