Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. 1.Prophase:- It is the first visible stage in karyokinesis.The chromosomes appear as long coiled threads called chromatids.The chromatin becomes shorter, thicker and visible due to the condensation of DNA.The chr...
Stages of Mitosis. Learn about the steps of mitosis, including what occurs in the cell at each stage and the main differences between mitosis and meiosis. Related to this QuestionExplain the process of mitosis. Describe the events that occur in the four phases of mitosis (prophase, metaph...
In the first meiotic division (MI) of oocytes, the cortically positioned spindle causes bivalent segregation in which only the centre-facing homologue pairs are retained. ‘Selfish’ chromosomes are known to exist, which bias their spindle orientation and hence retention in the egg, a process known...

a. Explain how Down's syndrome happens: which chromosome(s) are affected? b. At what stage in meiosis does the failure to separate occur? c. What are some of the symptoms associated with these conditions? Why do diseases like ...
What happens during prophase I of meiosis? How does the anaphase of mitosis differ from the anaphase i of meiosis? What happens in meiosis I that does not occur in meiosis II? What do chromosomes do in meiosis but not in mitosis?
Explain the main difference between mitosis and meiosis. What is a haploid gamete? How does meiosis get its diploid cell? Are germ cells haploid or diploid? In the diploid stage, how are there gametes when there is only one set of chromosomes (n)?
What is cell cycle, and what occurs at each stage? What are the three phases of the cell cycle? Describe the different stages of the cell cycle. Include the following stages: 1. Interphase - G1 2. Interphase - S 3. Interphase - G2 4. Prophase 5. Prometaphase 6. Metaphase 7. Anaph...
Explain the complete process of mitosis and meiosis. During which phase of meiosis does crossing over take place? Explain why it is only during this phase. Cite any source(s) used. Crossing-over occurs between the four-stranded paired homologous chromosomes ...
