What are the 4 mitotic stages?

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

Which stage of mitosis is pictured in the micrograph below from an onion Allium root tip?

metaphase
The photomicrograph below depicts onion root tip cell chromosomes in metaphase, ready for separation.

Why is Allium Cepa used in studying mitosis?

The size of chromosomes makes Allium cepa tips as favourable material for the study of the effects of chemicals on frequency of CAs which are biomarkers of damage of genetic material.

What happens in each stage of mitosis?

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

What are the different stages in mitosis that you were able to observe?

There are 5 different stages of mitosis that can be observed namely; interphase, prophase, metaphase, anaphase and telophase. By using certain chemicals to stain the cells, most of the cells can be observed under different stages of mitosis.

What is Allium root tip?

Allium root tip: Examine the square cells just inside the root cap. This is the root meristem (embryonic tissue) where mitosis is occurring. Farther up the root is the elongation zone, where cells are long rectangles; these cells are not undergoing mitosis.

Why is colchicine called mitotic poison?

Mechanistically, colchicine inhibits microtubule polymerization by binding to tubulin, one of the main constituents of microtubules. In another sense, availability of tubulin is necessary to mitosis; hence colchicine effectively works as a “mitotic poison” or spindle poison.

What are the 5 stages of the cell cycle?

In eukaryotes, the cell cycle consists of a long preparatory period, called interphase. Interphase is divided into G1, S, and G2 phases. The mitotic phase begins with karyokinesis (mitosis), which consists of five stages: prophase, prometaphase, metaphase, anaphase, and telophase.
