Detailed explanation-1: -Cancer cells spend less time in interphase and reproduce rapidly before the cells have had a chance to mature. cells “hear” these signals they stop growing.
Detailed explanation-2: -Normal Cells spend most of their time in Interphase. Cancer Cells spend most of their time in Mitosis. Which of the following is NOT one of the three main phases of Interphase?
Detailed explanation-3: -In cancer, the cells often reproduce very quickly and don’t have a chance to mature. Because the cells aren’t mature, they don’t work properly. And because they divide quicker than usual, there’s a higher chance that they will pick up more mistakes in their genes.
Detailed explanation-4: -The cell usually spends most of its time in interphase and spends a very small amount of time in actual cell dividing phases. However, cancer cells are in a rapid state of cell division and spend much more time out of interphase.
Detailed explanation-5: -Abstract. Human cancers have an apparent low growth fraction, the bulk of cells presumed to being out of cycle in a G0 quiescent state due to the inability in the past to distinguish G0 from G1 cells.
