EXPLAIN BRIEFLY THE DIFFERENT STAGES OF MITOSIS?

Sagot :

soeliashira

Answer:

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeresp

2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell)

3) Anaphase: sister chromatids are pulled to opposite poles of the cell

4) Telophase: nuclear envelope ..

The stages of Mitosis are:

1. Prophase

2. Metaphase

3. Anaphase

4. Telophase.

Only two pairs of chromosomes are shown in the diagrams below. There are 23 pairs of chromosomes in a diploid human body cell.

Stages of Mitosis and their Meanings:

Prophase-

It is the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.

Metaphase-

It is the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.

Anaphase-

It is the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.

Telophase-

Telophase is the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.

Let's Remember other meanings!

TELOPHASE

The final stage of cell division, in which membranes form around the two groups of chromosomes, each at opposite ends of the cell, to produce the two nuclei of the daughter cells. In mitosis, telophase is preceded by anaphase.

PROPHASE

Prophase is the starting stage of cell division in eukaryotes. Prophase, in both mitosis and meiosis, is recognized by the condensing of chromosomes and the separation of the centrioles in the centrosome.

ANAPHASE

Anaphase is the stage of mitosis after the process of metaphase when replicated chromosomes are split and the newly-copied chromosomes are moved to opposite poles of the cell.

METAPHASE

A stage in mitosis or meiosis during which the chromosomes align along the equatorial plane of the cell and kinetochores contact the microtubule of the spindle apparatus.

Words that are underlined: Meanings

Eukaryotes:

Eukaryotes are an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than eubacteria and archaebacteria.
