Within every cell, there are genes that tell the cell when to start the process of DNA replication and mitosis and when to stop. There are also "checkpoint" genes that will interrupt or stop cell division if a problem occurs.

Which of the following factors might cause checkpoint genes to interrupt cell division?
Check all that apply
A. Neurological signals sent from the brain tell the cell to stop
B. The cell's DNA has been damaged somehow
C. There are not enough nutrients to support cell division

B. The cell's DNA has been damaged somehow

Explanation:

Cell division is a must for every living cell. Before a cell can divide, its genetic material (DNA) needs to be duplicated. However, all conditions necessary for the DNA replication and actual division (mitosis or meiosis) must be favorable. The set of genes that makes sure of this are called CHECKPOINT genes. Checkpoint is an internal controlled mechanism employed by the cell to ensure that its division occurs without errors. Any errors during this process can cause the cell division process to be halted.

Checkpoints occur after certain stages of the cell cycle and each is dependent on whether certain demands are met by the cell. For example, the G1 checkpoint will not allow S-phase (Synthesis of DNA) to take place if it is observed that the DNA of that cell has been damaged in any way. The cell using checkpoints prevent that cell from dividing and multiplying in order not to magnify the problem.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
