|
|
The time length becomes much longer because it takes longer for the abnormally small cells to grow to continue the cell cycle.
|
|
|
The time length becomes much shorter because the cancerous cells are unable to continue cell division.
|
|
|
The time length becomes much longer because the cancerous cells take longer to complete the Gap 2 phase.
|
|
|
The time length becomes much shorter because the abnormally small cells stop growing sooner than normal

Detailed explanation-1: -Conclusion. Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
Detailed explanation-2: -The length of the cell cycle is important because it determines how quickly an organism can multiply. For single-celled organisms, this rate determines how quickly the organism can reproduce new, independent organisms.
Detailed explanation-3: -This shortening is thought to be one of several factors that causes cells to age. A cell can no longer divide when telomeres are too short-once they reach a critical point, the cell becomes inactive (or ‘senescent’), slowly accumulating damage that it can’t repair, or it dies.
Detailed explanation-4: -The duration of these cell cycle phases varies considerably in different kinds of cells. For a typical rapidly proliferating human cell with a total cycle time of 24 hours, the G1 phase might last about 11 hours, S phase about 8 hours, G2 about 4 hours, and M about 1 hour.
