Biology 1110 Laboratory Mitosis – Excellent presentation of mitosis at high school level. Mitosis is essential for growth and repair. Although the process of mitosis is often segregated, for descriptive purposes, into four or more discrete phases based on the appearance and behavior of chromosomes, the entire cell cycle is a dynamic event that occurs continuously without pause.

During the G 1 phase, daughter cells formed in the previous M phase undergo active cell growth.
During cell division, the cell nucleus splits and the DNA is replicated. Provides actual pictures of cells and explanations of each phase of Mitosis and Cytokenesis. The characteristic which had disappeared and had now reappeared Mendel described as recessive. Prophase II, Metaphase II and Anaphase II resemble mitosis but with only a haploid chromosome number. Meiosis differs from mitosis primarily because there are two cell divisions in meiosis, resulting in cells with a haploid number of chromosomes. Metaphase This sets the stage for chromosome separation in the next stage of mitosis: anaphase.

For example, animal life cycles have a dominant diploid phase, with the gametic (haploid) phase being a relative few cells. The other structures important for mitosis are also forming (i.e. the centrioles).

Crossing over – We cannot see it but at this point portions of one chromatid of one homologue may become exchanged with the corresponding region from a chromatid of the other homologue. This ensures that they will be genetically identical to each other and to the cell from which they originated. In humans, mitosis produces somatic cells that are diploid, which means they contain two non-identical copies of each of the twenty-three chromosomes.
