Question

Which of the following processes takes roughly 90-95% of the time of cellular division?

a. Interphase
b. Mitosis
c. Cytokinesis
d. All of the above each take roughly the same amount of time
e. None of the above participate in cellular division

Answer 1

Interphase is the phase that takes up 90-95% of the cell cycle time, where the cell prepares for division by growing and replicating DNA.

Step-by-step explanation:

The process that occupies roughly 90-95% of the cell cycle is interphase. During interphase, the cell conducts its regular functions, grows, and prepares for division by undergoing three major sub-phases: the first growth phase (G1), the synthesis phase (S), where DNA replication occurs, and the second growth phase (G2). Although mitosis (with its stages of prophase, metaphase, anaphase, and telophase) and cytokinesis are important for cell division and take between 1 and 2 hours combined, they represent a relatively short fraction of the time in the cell's life cycle as compared to interphase.

Accordingly, the correct answer to the question is '. Interphase', where cells perform their 'everyday' functions and prepare for mitosis.

The process that takes roughly 90-95% of the time in cellular division is interphase. During interphase, the cell grows and carries out its normal functions, as well as prepares for cell division. It is the longest phase of the cell cycle and consists of three stages: G1, S, and G2.
