Which stage does daughter chromosomes arrive at the poles?

Which stage does daughter chromosomes arrive at the poles?


During which phase chromosomes are arranged at the poles?

During telophase, the chromosomes arrive at the cell poles, the mitotic spindle disassembles, and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes. Phosphatases then dephosphorylate the lamins at each end of the cell.

At which phase of mitosis do the sister chromatids become daughter chromosomes?


In what part of the cell cycle do the chromosomes reach the poles of the cell and detach from the mitotic spindles?

Chromosomes reach the poles of the cell during metaphase. The nuclear membrane goes away during prophase. The first stage of mitosis is telophase. The centrioles move to the poles of the cell during prophase.

Which of these cells reproduce at the slowest rate?

  • histone core.

What cells reproduce faster?

Prokaryotes in general reproduce much faster than multicellular eukaryotes.

Why does a cell multiply?

Cells multiply in order for the organism to grow, develop, repair and for the organism to produce offspring. If the cell divides, the same amount of volume now has two cell surfaces, or twice the surface area with which to interchange substances with its environment. …

What is the life of cell?

Most eukaryotic cells live according to an internal clock; that is, they proceed through a sequence of phases, called the cell cycle, during which DNA is duplicated during the synthesis (S) phase and the copies are distributed to opposite ends of the cell during mitotic (M) phase (Figure 1-9).

How the life span of a cell is decided?

The maximum lifespan of a human cell is given by its differentiation status (which has a lot to do with the Hayflick limit as mentioned by Kumar Adarsh) and partly by the environment. The environment can make a cell divide more or less often. The environment can make a cell divide more or less often.

Which is the smallest cell in female body?

The Cerebellum’s Granule Cell is the smallest cell in the human body that is between 4 micrometers to 4.5 micrometers long. The RBC ‘s size also found roughly 5 micrometers. The largest cell is ovum in the human body. The ovum also called egg cell is the reproductive cell in the female body.

Which is the largest cell in animal life?

The largest cell is an ostrich egg, it is about 15cm to 18 cm long and wide.

Why is a female egg cell so large?

Eggs are very big cells. In fact, they are the biggest cells in the human female body. Like a sperm cell, the egg contains a nucleus with half the number of chromosomes as other body cells. Unlike a sperm cell, the egg contains a lot of cytoplasm, the contents of the cell, which is why it is so big.
