During which stage of mitosis are chromosomes lined up in the center of the cell? During which phase of mitosis do the chromosomes line up along the middle of the dividing cell? How many chromosomes are visible at the beginning of mitosis?
Chromosomes During MitosisIn this part on the movement of chromosomes, the so-called normal behavior of the chromosomes during the processes of cell division and cell union will be discussed. These two processes guarantee the continuation of species from one generation to the next....
Prophaseis the first phase of mitosis. During this phase, the chromosomes inside the cell's nucleus condense and form tight structures. In fact, the chromosomes become so dense that they appear as curvy, dark lines when viewed under a microscope (Figure 1). Because each chromosome was duplicat...

Features of higher-order chromatin organization—such as A/B compartments, topologically associating domains and chromatin loops—are temporarily disrupted during mitosis1,2. Because these structures are thought to influence gene regulation, it is important to understand how they are re-established after...
Why do chromosomes condense during prophase? Explain the main difference between mitosis and meiosis. How does meiosis create genetic diversity? How are mitosis and meiosis similar and different? In meiosis, what makes up a tetrad? How do the genetic contents of cells resulting from mitosis and ...

D 0.5uM的GC-20作用下异常有丝分裂后期时,纺锤丝不能正确捕捉染色体,没有完成双极对向性附着, When C normal mitosis later period, the spindle fiber can catch the chromosome correctly, completes the double pole to adhere to stick cohere to tropism, and pulls the chromosome to the two-pole pulls,...
during Prophase I and Metaphase I. However, these chromosomes are not arranged in the same way as they were during mitosis. Rather than each chromosome lining up individually across the center of the cell, homologous pairs of chromosomes line up together (formingtetrads, also known asbivalents)...
Before chromosomes segregate into daughter cells, they align at the mitotic spindle equator, a process known as chromosome congression. Centromere-associated protein E (CENP-E)/Kinesin-7 is a microtubule plus-end-directed kinetochore motor required for congression of pole-proximal chromosomes. Because...
