Use the two images to complete the activity.
The first stage shows a nucleus inside a cell. The second stage shows the nucleus consisting of two pairs of chromosomes with microtubules. The third stage shows the chromosomes lining up with the help of spindles. The fourth stage shows the chromosomes vertically lined up and both the microtubules are attached to each chromosome through the spindles. The fifth stage shows both the microtubules pulling and dividing the chromosomes in half, forming two sets of chromosomes. The sixth stage shows the cell getting divided into two parts. The seventh stage shows two separate cells, each with its own nucleus.
The cell cycle begins with interphase, where the cell takes approximately 10 hours to grow. If it passes the G1 checkpoint, the DNA duplication starts and goes on for approximately eight hours. The cell further grows for approximately four hours. After passing the G2 checkpoint, the process of mitosis takes place, which takes approximately one to two hours. The phases during mitosis are prophase, metaphase, anaphase, telophase, and cytokinesis. After cytokinesis, the daughter cells enter interphase, and the cycle gets repeated.
In three to five sentences, describe the advantages and disadvantages of these maps in modeling mitosis.
The advantages of these maps in modeling mitosis are that they provide a visual representation of the stages of mitosis, making it easier to understand and remember. The use of images also allows for a step-by-step understanding of the process, aiding in comprehension. Additionally, the maps clearly show the duration of each stage, providing a sense of the time scale of mitosis.
However, a disadvantage of these maps is that they oversimplify the complex process of mitosis. Mitosis involves various intricate biochemical and molecular events that are not depicted in these images. Additionally, the maps do not provide any information on the specific functions and roles of the different structures involved in mitosis, which is crucial for a comprehensive understanding.
