Checkpoint isone of the secure firewalls. The main reason I am using this firewall is, its providing high-level security. Our organization has been using this firewall for over three years as a perimeter firewall. ... Also, Checkpoint helps to segregate the internal network. How do you ma...
Metaphase isthe third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. ... There is an important checkpoint in the middle of mitosis, called the metaphase checkpoint, during which the cell ensures ...
We use two systems to investigate meiotic division during spermatogenesis in the mouse: pharmacological induction of meiotic metaphase in cultured spermatocytes and transillumination-mediated dissection of stage XII seminiferous tubule segments to monitor progress through the division phase. By these approache...
Explain the basic phases of the cell cycle and identify the main checkpoints. What is the cell component that is visible only in cell division stages? What are the three phases of cell communication? Briefly describe each phase. What stage of the cel...
A mechanism producing chromosomal instability, triggered by the fusion of deprotected telomeres, which leads to repeating cycles of chromosome breakage and fusion. Fragile telomeres Breaks or gaps at telomeres of metaphase chromosomes, caused by replication stress. Fragile sites Genomic regions that appear...
In meiosis, what is the purpose of crossing over? What is the importance of mitotic cell division? What is the most basic purpose of mitosis and the cell cycle? How does the cell control these processes? What are checkpoints and apoptosis?

so the homologous chromosomes separate. Sometimes the enzymes topoisomerase II or separase are inactivated, causing chromosomes to stick together. Other times, the fault is with condensin, a protein complex that assembles chromosomes on the metaphase plate. A problem may also arise when the cohesin...
As mentioned above, there are two stages of meiosis—meiosis I and meiosis II—each of which include their own prophase, metaphase, anaphase and telophase. If the chromosomes fail to separate during either anaphase I or anaphase II, a case of aneuploidy occurs. Such an occurrence is known ...
What are the checkpoints at interphase, and what is the significance of each one? In what phase does DNA synthesis occur? a. anaphase b. telophase c. prophase d. metaphase e. interphase What is the process of cell division, growth, and replication of DNA called? How is DNA replication ...
