Describing the cell cycle and mitosis.

The cell cycle is the life of a cell from the time it is front formed from a dividing parent cell until its attempt section into devil cells. Cell class involves the distribution of equivalent DNA to 2 daughter cells. A dividing cell duplicates its DNA, allocates the cardinal 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 inclose into chromosomes. Eukaryotic chromosomes are made of chromatin. Each duplicated chromosome has two sister 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 peerless cell, there are now two, each the genetic alike 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 well-nigh 90% of the cell cycle. t is during interphase that the cell ages and copies its chromosomes in formulation for cell division. Interphase can be divided into subphases: the G1 phase ( firstly gap), the S phase (synthesis), and the G2 phase ( minute 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 five stages: prophase, prometaphase, metaphase, anaphase, and telophase. The mitotic arbor, made of microtubules and associated proteins assemble an d elongate. The assembly of spindle microtub! ules starts at the centrosome. During interphase, the flair centrosome replicates, forming two centrosomes, which remain to fither near the nucleus. The two centrosomes cash in ones chips apart from each other during prophase and prometaphase of mitosis, as spindle microtubules grow out from them. By the end of...
