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… WebAt the end of prophase, each of these 46 chromosomes contains two identical chromatids.

WebScore: 5/5 (13 votes) . The key difference between interphase and prophase is that a cell spends a lot of time in interphase undergoing protein synthesis, DNA replication, and growth while the cell spends a short time in prophase by undergoing condensation of chromatin, pairing of homologous chromosomes and spindle fiber formation. WebSuppose the two genes are on two different chromosomes, now we will track two pairs of chromosomes during meiosis. Watch the animation of how the three pairs of chromosomes align and separate at the end of the meiosis. Image one gene is on one pair of chromosome and the other one is in another pair of chromosome.

WebThe aim of the mitotic process is to segregate the genetic material packed into duplicated chromosomes equally between two daughter cells.
