Question

while researching, cancer, angel discovered a lot of information about what happens in a cell to cause the uncontrolled growth that is characteristic of cancer which of during the g₁ phase of the cell cycle, the dna continued to replicate repeatedly causing it to grow into a cancerous tumor. dna replication did not occur during the cell cycle which caused increased cellular content resulting in a cancerous tumor. a checkpoint during the m phase of the cell cycle was over activated and stimulated which caused the cell to swell resulting in a cancerous tumor. a mutation, which affected one of the check points during the cell cycle, caused the cell to continue to grow resulting in a cancerous tumor.

Explanation:

El cáncer se produce cuando una mutación afecta los puntos de control del ciclo celular, lo que hace que la célula crezca de manera no controlada. En la fase G₁, la replicación del ADN no ocurre repetidamente (eso ocurre en la fase S). Si no hay replicación del ADN, no se produce un tumor canceroso (ya que la célula no se dividiría adecuadamente). Los puntos de control del ciclo celular (especialmente en las fases G₁, S y G₂) son esenciales para detener la división celular dañada. Si un punto de control (por ejemplo, en G₁ o G₂) está mutado y no funciona, la célula dañada continuará creciendo y dividiéndose, lo que conduce a un tumor canceroso. En la fase M, los puntos de control se centran en la mitosis (división nuclear) y la citocinesis (división celular). Si un punto de control en M está sobreactivado, no causaría un tumor (más bien, podría detener la división celular).

Answer:

A mutation, which affected one of the check points during the cell cycle, caused the cell to continue to grow resulting in a cancerous tumor.
