Cell cycle and mitosis phases

The cell cycle in eukaryotic cells

The set or series of successive growth and division events that the cell travels throughout its life.

Is divided in

Interphase

Mitosis

Cytokinesis

Is the first phase of the cell, is made up of:

G1 Period of growth

Is when the cell is dedicated to grow and duplicate its organelles, to perform specific metabolic functions, and accumulate material.

S DNA replication phase

Is when the cell replicates its DNA that is in the form of chromatic.

The cell prepares division, the chromatin condenses and become visible as a chromosome.

Have an X-like structure.

Which join a narrow place called a centromere.

G2 The cell prepares for its division

Is where the cell continues to replicate its organelles and synthesize proteins that will be necessary or the cell division.

Is defined as the process of cell division in which a progenirtor cell give rise to 2 daughter cells with the same genetic.

Prophase

Metaphase

Anaphase

Telophase

The chromosomes are easily visible when viewed using a light microscope.

Small tubes called microtubules originate from the centrioles and form a dynamic called mitotic spindle.

Microtubules adhere to the chromosomes in a protein structure called cinetocorus.

Chromosomes are arranged in the center or equatorial plane of the cell, controlled by microtubules.

The third stage of mitosis, the chromosomes separate into 2 chromatids that make them up, going to oppositive ends of cell.

The microtubules are diasassembled, the nuclear membrane is restructures around eachgroup of chromosomes, so that the cell has to nuclei.

Is in which the cytoplasmatic membrane begins to invaginate, and together with the ring composed of actin and myosin proteins press the center of the cell until it separates into two.

One the cytokinesis is complete, the cell is ready to start again the interphase where it will grow and perform its metabolic functions.
