In which phase of mitosis do chromosomes arrive at opposite sides of the cell? (a) Anaphase (b) Prophase (c) Metaphase (d) Telophase (e) Interphase. During what phase of mitosis does the mitotic spindle begin to form? During which phase does crossing-over occur?...
Finally, we need to know the cell organelle which plays an important part in mitosis/meiosis. They are centrosomes. Centrosomes are made up of microtubules andcentrioles. Microtubules form the spindle fibers and centrioles help organize the spindle into proper formation. Now we can pay to att...

a秋水仙素能抑制细胞有丝分裂时形成纺锤体,但不影响染色体的复制,使细胞不能形成两个子细胞,而染色数目加倍。 The colchicin can suppress when the cell mitosis forms the spindle, but does not affect the chromosome the duplication, enables the cell to form two sub-cells, but dyes the number double...
In this study, we found interesting two-cell stage embryos, which had a monopolar spindle in one blastomere and a bipolar spindle in the other during the second mitosis in a batch subjected to tetraploidization treatment. These embryos have a high potential of developing diploid–tetraploid ...
Under when B0.5uM GC-20 function unusual mitosis intermediate stage, the spindle can form, the spindle fiber is obvious, but cannot catch the chromosome correctly, cannot form the double pole to adhere to stick cohere to tropism, B' Aurora B and INCENP appear the dissemination not to be abl...

What happens in each mitosis phase? There are four stages of mitosis: prophase, metaphase, anaphase and telophase.1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres 2) Metaphase: chromosomes line up along the metaphase...
What is the role of the spindle fibers during mitosis? How does the excretory system work with the immune system? Why do cells in the stratum corneum undergo molting? Explain why the lymphatic system is a one-way system. Explain the endocrine system ...
