Is prophase the shortest stage?

What is the shortest stage of cell cycle?

The shortest stage of the cell cycle is called cytokinesis (division of the cytoplasm). In cytokinesis, the cytoplasm and its organelles divide into two daughter cells. contains a nucleus with an identical set of chromosomes.

Which phase has shortest duration?

And then chromatids are moving to opposite poles. This phase spends 0.8% is the cell cycle , hence is the shortest cycle. D. S-Phase :- S or Synthesis phase is the phase during which DNA synthesis or replication is taking place.

Which is the shortest stage of prophase 1?

Leptotene- This is the first stage of prophase I and the shortest phase of prophase I.

  • It the phase of a replicated chromosome condensation.
  • The chromosomes condense and become compact and visible hence making it possible to distinguish between sister chromatids.

Is prophase the longest stage of mitosis?

Prophase. … The first and longest phase of mitosis is prophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope (the membrane surrounding the nucleus) breaks down.

Why is prophase the longest phase?

the longest phase of mitosis is prophase because in this phase many structure disappear like nucleus membrane and nucleolus at late prophase nd in early phrophase stage centriole become start dividing and shall go to the pole and mid phrophase stage centriole takes position at 90° between each other and lastly at the …

Is the nucleus present in prophase?

During prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes ( sister chromatids ).

Why is the anaphase the shortest phase?

The kinetochore microtubules shorten as the chromatids are pulled toward opposite poles, while the polar microtubules subsequently elongate to assist in the separation. Anaphase typically is a rapid process that lasts only a few minutes, making it the shortest stage in mitosis.

Which of the following occurs during prophase?

During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell. As the centrioles move, a spindle starts to form between them.

During which stage of prophase first the crossing over takes place?

During meiosis I in prophase I, crossing over takes place.
