Which of the following are principal stages of cell division mitosis and interphase synthesis and cytokinesis the M phase and the S phase mitosis and cytokinesis
Mitosis and Cytokinesis
The principal stages of cell division are mitosis, interphase, and cytokinesis. Among the options you provided, mitosis and cytokinesis are the correct stages.
To understand this, let me break it down:
1. Interphase: This is the longest phase of the cell cycle, during which the cell prepares for division. It's further divided into three subphases:
a. G1 Phase (Gap 1): The cell grows, performs its normal functions, and duplicates organelles.
b. S Phase (Synthesis): DNA replication takes place, resulting in the duplication of the entire genome.
c. G2 Phase (Gap 2): The cell continues to grow and prepare for mitosis.
2. Mitosis (M Phase): Mitosis is the process of nuclear division in eukaryotic cells. It can be divided into several stages:
a. Prophase: The nuclear envelope dissolves, and chromosomes condense.
b. Metaphase: Chromosomes line up at the center of the cell.
c. Anaphase: Sister chromatids separate and move to opposite poles of the cell.
d. Telophase: New nuclear envelopes form around the sets of separated chromosomes.
3. Cytokinesis: This is the final stage of cell division when the cytoplasm divides, resulting in the formation of two daughter cells. In animal cells, it typically occurs through the formation of a cleavage furrow, while in plant cells, a cell plate forms to divide the cytoplasm.
So, in conclusion, the principal stages of cell division are interphase, mitosis, and cytokinesis.
The principal stages of cell division are as follows:
1. Interphase: This is the phase where the cell prepares for division. It is further divided into three stages: G1 phase, S phase, and G2 phase.
2. Mitosis: This is the phase where the nucleus divides, resulting in the formation of two identical daughter nuclei. Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase.
3. Cytokinesis: This is the final stage of cell division, where the cytoplasm divides, and two daughter cells are formed.
So, among the options provided, the correct answer would be "mitosis and cytokinesis."
