how many hours is the interphase, the time in the cell cycle that is not devoted to mitosis? 1.1hour 2.10hours 3.9hours 4.half-hour 5.21hour
To determine the duration of the interphase in the cell cycle, we need to know the relative lengths of each phase within the cell cycle. The cell cycle consists of three main phases: interphase, mitosis, and cytokinesis.
During interphase, the cell undergoes normal growth, carries out its normal functions, and prepares for division. Interphase is further divided into three subphases: G1 phase (1st gap phase), S phase (synthesis phase), and G2 phase (2nd gap phase).
The majority of the cell cycle is spent in interphase, and it accounts for approximately 90% of the total cell cycle duration. This means that the remaining 10% is allocated for mitosis and cytokinesis.
Since the total cell cycle duration varies among different types of cells and organisms, we cannot provide an exact number of hours for the interphase without additional information. However, we can definitively conclude that the interphase is not as short as 1.1 hour, half an hour (0.5 hour), or 21 hours.
Considering the available options, the most plausible answer would be 9 hours (option 3), as this duration reasonably aligns with the typically observed lengths of the interphase in various cell types. However, it is important to note that the length of the interphase can vary depending on the specific cell and its requirements.
