Question

Due to the time it takes for space travel, to reach the new moon on Saturn, the Department of Defense has rockets traveling to it with babies growing in artificial incubators. Your job is to monitor cell duplication remotely. The Human cell cycle has which of the following phases?

Answer 1

Answer:

The human cell cycle has two main phases: the interphase and the M phase

Explanation:

Just like every cell, the human cell cycle has two main phases which are;

• The interphase
• The M phase

The interphase phase is further divided into 4 respective sub-phases namely;

• $G_0$ phase which is essentially a resting/quiescence phase. It  reserved for cells that have no need to divide unless they are called upon.
• $G_1$ phase, a phase where cell growth and development takes place.
• S phase, a phase where DNA is synthesized.
• $G_2$ phase, a phase where protein is synthesized.

The M phase is known as the active division phase. M can be mitosis or meiosis depending on the type of cells. Reproductive/sex cells will undergo meiosis while somatic/vegetative cells will undergo mitosis.

Mitosis is further divided into prophase, metaphase, anaphase and telophase while meiosis is divided into prophase I, metaphase I, anaphase I, telophase I and prophase II, metaphase II, anaphase II, telophase II respectively.
