Prophase of mitosis under microscope
WebbThe process of mitosis is divided into five identifiable stages: prophase, prometaphase, metaphase, anaphase and telophase (Figure 1). Prophase: the nuclear membrane begins to dissolve and chromatin begins to condense to from chromosome pairs connected by a centromere. Sister chromatids, resulting from duplication of each chromosome pair Webb4 feb. 2004 · The first phase of mitosis is known as the prophase, where the nuclear chromatin starts to become organized and condenses into thick strands that eventually become chromosomes. During prophase, …

As in mitosis, the chromosomes begin to condense, but in meiosis I, they also pair up. ... You can see crossovers under a microscope as chiasmata, cross-shaped structures where homologues are linked together.
WebbStephen M. Wolniak. Mitosis is the process that facilitates the equal partitioning of replicated chromosomes into two identical groups. Before partitioning can occur, the chromosomes must become aligned so that the separation process can occur in an orderly fashion.

WebbScientists define the following phases the division: interphase, prophase, prometaphase, metaphase, anaphase, telophase, press cytokinesis (Reece and et al., 2013). Each phase looks very differently from each other under microscope. The figure shows as onion root tip looks under microscope during mitosis (Kasili, 2016. p.26).
Prophase is the first stage of mitosis in animal cells, and the second stage of mitosis in plant cells. At the start of prophase there are two identical copies of each chromosome in the cell due to replication in interphase. These copies are referred to as sister chromatids and are attached by DNA element called the centromere. The main events of prophase are: the condensation of chromosomes, the movement of the centrosomes, the formation of the mitotic spindle, and the b… sustainability new product developmentWebbThe distinguishing features at each stage of Meiosis I.

By using certain chemicals to stain the cells, most of the cells can be observed under different stages of mitosis. Thus, the percentage of cells in each phase and the duration for each phase can be calculated.
