Answer:

They initiate various stages of the cell cycle.

Explanation:

Cyclins and cyclin-dependent protein kinases function to control the cell cycle. A group of cyclins: the G1 cyclins, are synthesized during G1 phase and function to activate CDPKs which initiate DNA synthesis at the G1/S checkpoint. The cell fails to progress to S phase if there is no sufficient synthesis of G1 cyclins. After a cell passes through this point, the G1 cyclins are degraded, allowing for another group of cyclins: the M cyclins to be synthesized. M cyclins activate a second group of CDPKs which allow the cell to pass the G2/M control point and into mitosis.

A child is prescribed hematopoietic stem cell transplantation for severe combined immunodeficiency disease. what is administered

mezya [45]

The child is administered to use Intravenous immunoglobulin and Pneumocystis caranii pneumonia or PCP prophylaxis. These are used to improve humoral immunity in the child until the time when the transplant is performed.
The child is not recommended to use influenza vaccine in immunodeficiency disease reason being the possibility of acquiring influenza which is severe.
Again the child is not recommended to use varicella vaccine because it can lead to a risk of acquiring chicken pox.
For a child with PCP, we use Dapsone.
