Chromosome at the end of prophase
Did you know?
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… WebDuring which phase of cell division are homologous chromosomes paired? prophase I Meiosis I. Compared to mitosis, which can take place in a matter of minutes, meiosis is a slow process, largely because of the time that the cell spends in prophase I. During prophase I, the pairs of homologous chromosomes come together to form a tetrad or …

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.
