Describing the cell cycle and mitosis.

The cell cycle is the life of a cell from the rate it is front formed from a dividing parent cell until its rush section into devil cells. Cell variant involves the distribution of equal DNA to 2 daughter cells. A dividing cell duplicates its DNA, allocates the 2 copies to opposite ends of the cell, and then splits into daughter cells. The replication and distribution of so much DNA is manageable because the DNA molecules are case into chromosomes. Eukaryotic chromosomes are made of chromatin. Each duplicated chromosome has two sis chromatids. In its condensed form, the duplicated chromosome has a center at a centromere. Mitosis, the division of the nucleus, is usually followed immediately by cytokinesis, the division of the cytoplasm. Where there was one and only(prenominal) cell, there are now two, each the genetic invariant of the parent cell. The mitotic (M) phase, which includes both mitosis and cytokinesis, is usually the shortest part of the cell cycle. Inte rphase accounts for approximately 90% of the cell cycle. t is during interphase that the cell brings and copies its chromosomes in training for cell division. Interphase can be divided into subphases: the G1 phase ( world-class gap), the S phase (synthesis), and the G2 phase ( trice gap). During all three subphases, the cell grows by producing proteins and cytoplasmic organelles such as mitochondria and endoplasmic reticulum.

Mitosis is conventionally broken down into 5 stages: prophase, prometaphase, metaphase, anaphase, and telophase. The mitotic arbor, made of microtubules and associated proteins assembl e and elongate. The assembly of spindle micr! otubules starts at the centrosome. During interphase, the champ centrosome replicates, forming two centrosomes, which remain to fither near the nucleus. The two centrosomes run into apart from each other during prophase and prometaphase of mitosis, as spindle microtubules grow out from them. By the end of...
