Cell Cycle and Drug Interruption
At which checkpoint should the drug interrupt the cell cycle to keep DNA from replicating?
A. G1 Checkpoint
В. G2 Checkpoint
C. G2 and M Checkpoint
D. M Checkpoint
Answer:
The checkpoint where the drug should interrupt the cell cycle to keep DNA from replicating is the G2 Checkpoint.
Cell cycle has been defined as the cycle in which cell produces, grows, and divides. It consists of three main phases: G1 phase where the cell increases in size, S phase where DNA synthesis occurs, and G2 phase where the cell prepares to divide.
A cell is the basic unit of life, composed of various organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi apparatus, nucleus, and cytoplasm. Cells can be categorized into prokaryotic and eukaryotic cells, with eukaryotic cells being more advanced and containing organelles.
Therefore, it is crucial for a drug to target the G2 checkpoint in the cell cycle to prevent DNA replication and maintain cell integrity. This ensures proper cell division and function.
