During mitosis, how many chromosomes are present during interphase, prophase, metaphase, anaphase and telophase?
Solution
Cells need to assemble proteins (particularly chemicals) to complete the living cycles of development, multiplication, tissue fix, and so forth The hereditary data the cell needs to make proteins is put away in the DNA. DNA is situated in the core of eukaryotic cells.
Complete answer:
MITOSIS - Division of the nucleus and distribution of chromosomes in the two daughter cells. - Most creature cells partition (epithelial cells, platelets, and so on) aside from neurons and muscle cells. - In plants, just the meristem cells go through mitosis. These meristems begin the wide range of various plant tissues. - ensures that one cell starts two IDENTICAL daughter cells
IMPORTANCE of MITOSIS:
-It keeps the quantity of chromosomes consistent.
-permits development: from zygotes (one cell) to grown-up (billions of cells)
-begins new cells for tissue fixing.
The development of the chromosomes during mitosis is constrained by the centrioles and the mitotic shaft, which have a place with the cytoskeleton. The beginning stage is G2 of interphase: the DNA is duplicated, the atomic envelope is finished, and the cell has two centrioles. - Mitosis can be partitioned in the accompanying stages: - PROPHASE, METAPHASE, ANAPHASE and TELOPHASE.
PROPHASE:
- Chromatin begins to consolidate and chromosomes can be seen.
-Nucleolus vanishes.
- Centrioles begin to relocate to inverse sides of the cell, and begin to shape the microtubules of the mitotic shaft, which will help the chromosomes to move.
- The atomic envelope begins to vanish.
METAPHASE:
- Nuclear envelope has vanished.
- Chromosomes connect to the microtubules of the mitotic shaft and adjust in the focal point of the cell (central plate).
ANAPHASE:
-The sister chromatids of every chromosome are pulled separated to inverse posts of the cell as the axle microtubules abbreviate, and they become new chromosomes.
TELOPHASE:
The new chromosomes arrive at the two shafts of the cell and start to decondense to frame chromatin once more.
-Mitotic axle breaks down.
-Nuclear envelope begins to conform to each new core.
-Cytokinesis begins.
Note: Meiosis is back to back cell divisions (I and II), like mitosis, with no DNA duplication between them. The consequence of meiosis is 4 daughter cells that are haploid (n). Furthermore, the daughter cells are not indistinguishable: they contain a distinctive blend of qualities (hereditary recombination) because of the trading of pieces of homologous chromosomes (getting over) during the prophase of the principal meiotic division.
