Describing the cell cycle and mitosis.

The cell cycle is the life of a cell from the measure it is front formed from a dividing parent cell until its cause section into devil cells. Cell division involves the distribution of analogous DNA to 2 daughter cells. A dividing cell duplicates its DNA, allocates the two 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 incase 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 unrivaled cell, there are now two, each the genetic uniform of the parent cell.

The mitotic (M) phase, which includes both mitosis and cytokinesis, is usually the shortest part of the cell cycle. Interphase accounts for almost 90% of the cell cycle. t is during interphase that the cell grows and copies its chromosomes in preparation for cell division. Interphase can be divided into subphases: the G1 phase (first gap), the S phase (synthesis), and the G2 phase ( trice gap). During all three subphases, the cell grows by producing proteins and cytoplasmatic organelles such as mitochondria and endoplasmic reticulum.



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