Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. ... There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures that it is ready to divide.

Assuming a cell has just completed DNA synthesis, place these stages/steps in the cell cycle in the correct order of occurance b
shusha [124]

Answer:

The division of eukaryotic cell is done through various phase known as cell cycle.

Explanation:

The two basic phases of cell cycle is Interphase and Mitosis, that can be further divided into:

1) G2 Phase; G2 checkpoint ( Interphase stage)

2) Prometaphase (Mitotic Phase)

3) Anaphase  (Mitotic Phase)

4) Telophase  (Mitotic Phase)

5) cytokinesis (Mitotic Phase)

6) G1 Phase; G1 checkpoint ( Interphase stage)

After G1 phase there would be again S phase in which DNA replication occur.

A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 4 picograms of DNA
damaskus [11]

Answer:

b: 8;8

Explanation:

Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;

  • <em>the G_0 phase,</em>
  • <em>the G_1 phase,</em>
  • <em>the S phase; and</em>
  • <em>the G_2 phase</em>.

The G_0 phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.

Actively dividing cells enter the G_1 phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the G_2 phase where proteins are synthesized in preparation for division or m phase.

At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.

Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of G_2 phase.

The correct option is b.
