Definition Of Mitosis In Wikipedia

Strictly applied the term mitosis is used to describe the duplication and distribution of chromosomes the structures that carry the genetic information. The chromosomes of a cell are copied to make two identical sets of chromosomes and the cell nucleus divides into two identical nuclei.

Cell Division Mitosis And Meiosis Biological Principles

The polyploid macronucleus found in ciliates divides amitotically.

Definition of mitosis in wikipedia. Cell growth refers to an increase in the total mass of a cell including both cytoplasmic nuclear and organelle volume. Miosis or myosis is excessive constriction of the pupil. A type of cell division of somatic cells in which each daughter cell contains the same number of chromosomes as the parent cell.

Anisocoria is the condition of one pupil being more dilated than the other. Sexual reproduction takes place when a sperm. Karyokinesis is also known as mitosis.

Mitoses -sz Biology 1. In multi-celled eukaryotes mitosis is how a single zygote can become an entire organism. Mitosis a process of cell duplication or reproduction during which one cell gives rise to two genetically identical daughter cells.

Amitosis a- mitosis also called karyostenosis or direct cell division or binary fission. Before mitosis the cell creates an identical set of its own genetic information this is called replication. Miosis caused by high doses of opiates.

The process in cell division by which the nucleus divides typically consisting of four stages prophase metaphase anaphase and telophase and normally resulting in two new nuclei each of which contains a complete copy of the parental chromosomes. This process is important in single-celled eukaryotes as it is the process of asexual reproduction. It is generally followed immediately by cytokinesis which divides the nuclei cytoplasm organelles and cell membrane into two cells containing roughly equal shares of these cellular components.

Mitosis - cell division in which the nucleus divides into nuclei containing the same number of chromosomes cell division cellular division - the process in reproduction and growth by which a cell divides to form daughter cells. The opposite condition mydriasis is the dilation of the pupil. Mitosis is a part of the cycle of cell division.

Meiosis is a type of cell division in sexually reproducing eukaryotes resulting in four daughter cells gametes each of which has half the number of chromosomes as compared to the original diploid parent cell. The term is from Ancient Greek mein to close the eyes. The genetic information is in the DNA of the chromosomes.

It is cell proliferation that does not occur by mitosis the mechanism usually identified as essential for cell division in eukaryotes. Cell growth occurs when the overall rate of cellular biosynthesis production of biomolecules or anabolism is greater than the overall rate of cellular degradation the destruction of biomolecules via the proteasome lysosome or autophagy or catabolism. While normal mitosis results in a precise division of.

During mitosis replicated chromosomes in the parent nucleus are equally divided into two daughter nuclei through several sequential events known as phases. Meiosis is a special type of cell divisionUnlike mitosis the way normal body cells divide meiosis results in cells that only have half the usual number of chromosomes one from each pairFor that reason meiosis is often called reduction divisionIn the long run meiosis increases genetic variation in a way which will be explained later. Karyokinesis and cytokinesis are two steps in the cell division.

Mitosis is the process by which a eukaryotic cell separates the chromosomes in its cell nucleus into two identical sets in two separate nuclei. Mitosis Definition Mitosis is the step in the cell cycle that the newly duplicated DNA is separated and two new cells are formed. Mitosis is the process by which the body grows and dead somatic cells are replaced.
