Question

Which of the following is NOT true about the eukaryotic cell cycle?

There are two stages to the cell cycle: M phase and interphase.
Some cells pause between M phase and S phase for more than a year.
There are three phases of interphase: the S phase and two gap phases.
Interphase is typically the shortest of the two stages of the cell cycle.
The M phase consists of two events: mitosis and cytokinesis.

Answer 1

The false option is Interphase is typically the shortest phase of the two phases

Step-by-step explanation:

The cell cycle refers to the series of occurrences that occurs between the point of DNA duplication to the splitting of the cell into daughter cells. In eukaryotic cells, this process of cell cycle involves two distinct phases viz: the Interphase and the Mitotic (M) phase.

The Interphase involves three steps; G1 phase, S-phase and the G2 phase, where the cell undergoes growth, replicate its genetic material (DNA) and prepares for the mitotic phase generally. The interphase stage is the stage that occurs between two successive cell divisions, hence, it is at this stage the cell has time to grow and prepare itself for another round of division process. Due to this, it is the longest phase of the cell cycle in eukaryotes.

The cell enters the mitotic or M phase when it successfully completes the Interphase. The mitotic phase consists of: Mitosis and Cytokinesis.

Mitosis is when the separation of genetic material in form of chromosomes occur. It takes place in four stages viz: Prophase, Metaphase, Anaphase, Telophase. Cytokinesis is the division of the cytoplasmic content of the cell. It is the stage where the cell splits into two daughter cells containing individual chromosomes.
