Question

What part of the cell cycle has been disrupted to allow for the formation of cancer cells?.

Answer 1

Cancer cells form when there is a disruption in the cell cycle due to changes in the DNA sequence of genes that regulate the cell cycle.

Step-by-step explanation:

When a disruption occurs in the cell cycle, it allows for the formation of cancer cells. Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms regulating the cell cycle. This breakdown can occur due to changes in the DNA sequence of genes that code for regulatory molecules, leading to faulty instructions and nonfunctional proteins. As a result, the monitoring system of the cell cycle becomes disrupted, allowing for the passing on of mistakes to daughter cells and the accumulation of damage. This eventually leads to the formation of rapidly reproducing cancer cells that crowd out normal cells and result in tumorous growth.

Answer 2

Answer: DNA Synthesis

In many cancer cells, the number of chromosomes is altered so that there are either too many or too few chromosomes in the cells. These cells are said to be aneuploid. Errors may occur during the DNA replication resulting in mutations and possibly the development of cancer.
