  2. Mitosis - Wikipedia

    en.wikipedia.org/wiki/Mitosis

    Mitosis in the animal cell cycle (phases ordered counter-clockwise). Mitosis divides the chromosomes in a cell nucleus. Label-free live cell imaging of mesenchymal stem cells undergoing mitosis Onion cells in different phases of the cell cycle enlarged 800 diameters. a. non-dividing cells b. nuclei preparing for division (spireme-stage)

  3. Walther Flemming - Wikipedia

    en.wikipedia.org/wiki/Walther_Flemming

    The centrosome was discovered jointly by Walther Flemming in 1875 [1] [2] and Edouard Van Beneden in 1876. [3] [4] Flemming investigated the process of cell division and the distribution of chromosomes to the daughter nuclei, a process he called mitosis from the Greek word for thread. However, he did not see the splitting into identical halves ...

  4. Cell cycle - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle

    The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.

  5. Cytogenetics - Wikipedia

    en.wikipedia.org/wiki/Cytogenetics

    Following the advent of procedures that allowed easy enumeration of chromosomes, discoveries were quickly made related to aberrant chromosomes or chromosome number. [citation needed] Constitutional cytogenetics: In some congenital disorders, such as Down syndrome, cytogenetics revealed the nature of the chromosomal defect: a "simple" trisomy.

  6. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    Cell division in prokaryotes (binary fission) and eukaryotes (mitosis and meiosis). The thick lines are chromosomes, and the thin blue lines are fibers pulling on the chromosomes and pushing the ends of the cell apart. The cell cycle in eukaryotes: I = Interphase, M = Mitosis, G 0 = Gap 0, G 1 = Gap 1, G 2 = Gap 2, S = Synthesis, G 3 = Gap 3.

    Carl Wilhelm von Nägeli [1] [2] [3] (26 or 27 March 1817 – 10 May 1891) [3] [4] [5] was a Swiss botanist.He studied cell division and pollination but became known as the man who discouraged Gregor Mendel from further work on genetics.

  8. Cell theory - Wikipedia

    en.wikipedia.org/wiki/Cell_theory

    The cell was first discovered by Robert Hooke in 1665, which can be found to be described in his book Micrographia. In this book, he gave 60 observations in detail of various objects under a coarse, compound microscope. One observation was from very thin slices of bottle cork. Hooke discovered a multitude of tiny pores that he named "cells".

    Eduard Strasburger was born in Warsaw, Congress Poland, the son of Anna Karoline (von Schütz) and Eduard Gottlieb Strasburger (1803–1874). [2] [3] In 1870, he married Alexandra Julia ("Alexandrine") Wertheim (1847–1902), they had two children: Anna (1870–1942) and Julius (1871–1934).
