Longest phase of mitosis

But given the number of events taking place, and the time taken to prepare a cell for its division during Prophase is the maximum compared to all the other phases. It is also a point to be noted, that Anaphase is the shortest stage in Mitosis.

Which is the longest phase of meiosis?

Assertion [A]: Prophase I of Meiosis I is the longest phase during the formation of gametes.

Which phase is the longest?

The G1 phase is the longest in the cell cycle. It's the beginning of the interphase. The cell prepares for division during the G1 phase.

Which phase is the shortest in mitosis?

In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell.

Why is metaphase the longest phase of mitosis?

The longest phase of mitosis is prophase because During prophase, which occurs after G2 interphase, the cell prepares to divide by tightly condensing its chromosomes and initiates mitotic spindle formation. The chromatin fibers condenses into discrete chromosomes. The nucleolus also disappears during early prophase.

Which is the longest and shortest phase in meiosis?

Hint: The shortest phase is a part of Meiosis I in cell division. It involves the separation of homologous chromosomes, which start moving towards the opposite poles after they are aligned at the equator. Complete answer: The shortest phase of mitosis is Anaphase I.

Why is interphase the longest phase?

The interphase is the longest phase of the cell cycle because it is the stage during which all the preparation for cell division takes place.

What's the longest phase in interphase?

The synthesis phase of interphase takes the longest because of the complexity of the genetic material being duplicated.

What is the longest phase and why?

Thus Interphase is the longest phase in the life of a cell. Interphase: This is the period between two successive mitotic divisions. It is a period of active synthesis and intense growth.

What is the longest stage of a cells life?

Interphase is the phase of the cell cycle in which a typical cell spends most of its life. During interphase, the cell copies its DNA in preparation for mitosis. It is the longest stage of cell cycle.

What is the longest and most complex phase?

Solution : Prophase of mitosis is the longest phase.

Which is the shortest phase?

Anaphase is the shortest phase of mitosis. In anaphase, the sister chromatids are pulled apart to opposite ends of the cell. In metaphase, chromosomes line up along the metaphase plate.

How long does each stage of mitosis take?

The time required then for the complete process of mitotic cell division would lie within the following limits: Prophase, 30 to 60 minutes; metaphase, 2 to 10 minutes; anaphase 2 to 3 minutes; telophase 3 to 12 minutes and the reconstruction period from 30 t'o 120 minutes: total 70 to 180 minutes.

Which phase of mitosis is fastest?

The shortest phase of mitosis is anaphase, which comes after metaphase. In this phase, the sister chromatids separate and move towards opposite poles.

What is the fastest stage of the cell cycle?

Definition of the cell cycle:
The cell cycle refers to the series of events that take place in a cell, resulting in the duplication of DNA and division of cytoplasm and organelles to produce two daughter cells.
(i) M phase is considered the shortest phase in the cell cycle.

Why is mitosis the shortest phase?

Anaphase is the shortest phase of mitosis. In this phase, the spindle fibres contracts and this causes the centromere to split. The sister chromatids are then pulled apart to opposite ends of the cell. This phase last for about 2-3 minutes probably.

Which is longer mitosis or meiosis?

Mitosis involves only one cell division that is composed of four major phases: prophase, metaphase, anaphase, and telophase. Meiosis is quite longer as it involves two successive divisions that results to the reduction in chromosome number.

What are the 5 stages of mitosis?

These phases are prophase, prometaphase, metaphase, anaphase, and telophase.

What are the 8 stages of mitosis in order?

Phases of mitosis

Late G2 phase. The cell has two centrosomes, each with two centrioles, and the DNA has been copied.
Early prophase. ...
Late prophase (prometaphase). ...
Metaphase. ...
Anaphase. ...
Telophase. ...
Cytokinesis in animal and plant cells.

What is the hardest phase of mitosis?

DNA is most difficult to visualize at prophase stage of mitosis. Explanation: At prophase stage, no well defined chromosomes are present. DNA is present in the form of thin chromatin fibers that are difficult to visualize under microscope.
