Test Essay on Cell Division, Anatomy & Physiology Dr. Mann.

The Process of Mitosis is the term used to describe cell stratum for replication. This figure verboten is used for growth and repair within an existence and also for asexual reproduction. There are five chief(prenominal) stages to mitosis, called Interphase, Prophase, Metaphase, Anaphase and Telophase. Although the process has been divided up into these stages the process of mitosis is actually continuous. In Interphase, the archetypal stage, the cell is the original part. All cell organelles are mental hospital produced in quantity and the chromosomes (DNA molecules) are being copied exactly. The two same copies of DNA are called a pair of chromatids and they are call up to scramher by an item called a chromomere. In Prophase changes to the cell bleed visible. The chromosomes condense, coiling up to about 5% of their original length. The centrioles persuade to the enemy terminals of the cell and small microtubules around the centrioles become visible. The ther monuclear tissue layers and nucleolus disintegrate after passing their nucleic acids to real pairs of chromatids. forthwith a spindle forms, this is also made out of microtubules. During Metaphase, the chromosomes apparent movement towards the equator of the spindle, attaching themselves horizontally by the centromere to the spindles filaments. The chromatids so pull somewhat away from each other at the centromere towards the opposite terminuss of the cell.

Some spindle fibers run from pole to pole art object others from pole to equator. In this phase, in that respect is no nuclear membrane at all. Anaphase , the next step, is rattling quick. The pai! rs of chromatids are separated and each chromatid is pulled towards each opposite pole by the spindle fibers by a ratchet-like mechanism. This process requires muscle so the ATP stored is at present used up. They give apart by the centromere pause into two. Each centromere divides into two so that each...
