Virtual labs are a valuable tool for educators, students, and researchers. They allow us to explore complex scientific concepts and processes without the need for expensive equipment or risky experimentation. One such virtual lab is the Cell Cycle and Cancer virtual lab, which allows users to explore the mechanisms behind cell division and how it can go wrong in the development of cancer.
The cell cycle is the process by which cells grow and divide. It is made up of two main stages: interphase and mitosis. Interphase is the period of cell growth and DNA synthesis, during which the cell prepares for division. Mitosis is the actual process of cell division, during which the cell's nucleus and cytoplasm are divided into two identical daughter cells.
Cancer is a disease that is characterized by the uncontrolled growth and division of cells. It occurs when there are mutations in the DNA of a cell that cause it to divide and grow uncontroll. These mutations can occur in various genes that regulate the cell cycle, such as the tumor suppressor genes and oncogenes.
The Cell Cycle and Cancer virtual lab allows users to explore how mutations in these genes can lead to cancer. For example, mutations in tumor suppressor genes can cause cells to divide uncontroll, leading to the development of tumors. On the other hand, mutations in oncogenes can cause cells to divide more rapidly, leading to the development of cancer.
In the virtual lab, users can also explore the various treatments for cancer, such as chemotherapy and radiation therapy. These treatments work by targeting cells that are dividing rapidly, which is often a characteristic of cancer cells. However, these treatments can also damage healthy cells that are dividing, leading to side effects such as hair loss and nausea.
Overall, the Cell Cycle and Cancer virtual lab is a valuable resource for understanding the mechanisms behind cell division and how it can go wrong in the development of cancer. It allows users to explore the various genetic and environmental factors that can lead to cancer, as well as the various treatments available for this disease. Whether you are an educator, student, or researcher, the virtual lab is a valuable tool for exploring these complex concepts in a safe and convenient way.
Virtual Lab #3
Involving this cell cycle many cell do not undergo of complete the process of the cell cycle incorrectly which causes Cancer, which is when cells begin to grow out of control and continues making cells to the point where it out crowds normal cells. CENP-A CID in flies is the histone H3 variant essential for centromere specification, kinetochore formation, and chromosome segregation during cell division. Finally, we show that the centromere proteins CAL1 and CENP-C are both required for CID assembly in meiosis and normal progression through spermatogenesis. The second phase is Mitosis, which consist of Karyokinesis in the use of five sub phases known as Prophase, prometaphase, metaphase, anaphase, telophase. Interestingly, we observe a novel decrease in CID levels after the end of meiosis I and before meiosis II, which correlates temporally with changes in kinetochore organization and orientation.

Here we investigate the timing and requirements for CID assembly in mitotic tissues and male and female meiosis in Drosophila melanogaster, using fixed and live imaging combined with genetic approaches.

From the Monitor Video : Watch the video then complete the table by describing each phase of mitosis in your own words. This interactive module explores the phases, checkpoints, and protein regulators of the cell cycle. There are four types of phases as the cell progresses, Interphase, which contains multiple phases like G1, S, G2, M and G0.

Furthermore, CID assembly occurs at two distinct cell cycle phases during male meiosis: prophase of meiosis I and after exit from meiosis II, in spermatids. Students can toggle between two different views of the cell cycle by pressing the text in the center of the graphic. When finished, complete the analysis questions. . Cancer causes problems within the part of the body it started in and stay, known as benign, and can spread to other body parts, known as malignant. .
