Cell cycle

centrisome of cells and are primarily tasked with the creation of microtubules. The microtubules give way to mitotic spindles, which play a vital role in both mitosis and cytokinesis as they give cilia and flagellum the ability to generate motion and they ensure both newly formed cells contain paired centrioles during the later stages of cell division. Kinetochores are protein structures that produce chromosomal movement through the attachment of chromatids to spindle fibres and aid in cell…

better understand the cell cycle and the different phases of mitosis, students were expected to observe cell division in an onion root. I hypothesized that we would observe more cells in interphase since most of a cell’s life is spent in interphase. In order to make observations, we used a light microscope to view two slides of an onion root—one had been previously prepared while the other slide was made by each individual student. Furthermore, we then counted how many cells were in which phase…

Mitosis and Cancerous Cells Introduction Mitosis is by definition, “A type of cell division that results in two daughter cells each having the same number of chromosomes as the parent nucleus, typical of ordinary tissue growth.” Mitosis is a vital process to living organisms. Without mitosis, organisms could not grow, age, repair, or exist in general. Therefore, it is very important that the cell cycle is carefully controlled by the cell. This refers to is the limits set on cell division to…

Kaempferol is a natural polyphenol, secondary metabolite (flavonol), a type of flavonoid, found in a variety of plant-derived foods. Kaempferol is a yellow crystalline solid with a melting point of 276–278 °C. It is slightly soluble in water and highly soluble in hot ethanol, ethers, and DMSO. Kaempferol acts as an antioxidant by reducing oxidative stress. Many studies suggest that consuming kaempferol may reduce the risk of various cancers, and it is currently under consideration as a possible…

The results in this lab for Interphase had twenty cells, Prophase had ten cells, Metaphase had three cells, Anaphase has two and last Telophase, which had only one cell. The results shows that Interphase took the longest for completion and Prophase was the second longest for completion. Telophase took the shortest time for completion. The percentages for each mitosis stage and Interphase was fifty-six percent for Interphase, twenty-eight percent for Prophase, eight percent for Metaphase, six…

Mitosis is a process of cell division resulting in two genetically identical daughter cells developing from a single parent cell. Meiosis is a type of cell division resulting in the production of sperm or eggs that have half the chromosomes of the parent cell. Mitosis and meiosis are similar in a way that they are both ways in which cells reproduce. Mitosis and Meiosis both occur in humans and animals. In both cases (Mitosis and Meiosis), cells copy DNA and make new cells based on the…

in Saccharomyces cerevisiae. S. cerevisiae is a species of yeast in which goes through asymmetrical cellular division. Its lifespan is measured by the number of cellular divisions the mother cell is able to complete before death. In the research study by Kennedy et al, the researchers focused on yeast cells and how stress tolerance can extend lifespan through silencing genes, like SIR4. SIR4, a silencing gene, works with other SIR genes to form a SIR complex which regulates expression at regions…

and growth of a zygote. The two ways cell division can occur are through mitosis and meiosis. In mitosis, a cell produces two clones of itself, each with the same number of chromosomes. In meiosis, a cell will produce four cells called gametes through the process of spermatogenesis and oogenesis. Gametes are most commonly known as sperm cells in males and egg cell in females. Unlike mitosis, the gametes that meiosis produces are not clones of the original cell as each gamete has exactly had as…

Mitosis and meiosis are forms of cell division that produce daughter cells containing genetic information from the parent cell. Mitosis is the division of the genetic material in the nucleus which is immediately followed by cytokinesis. On the other hand, meiosis occurs in sexually reproducing organisms and this type of cell division reduces the sets of chromosomes from two to one in gametes. Both mitosis and meiosis differ, however, both processes result in daughter cells forming. In the end of…

of DNA and other proteins. Chromosomes are present in every cell of the human body so that information can be carried for that cell to develop. The human body normally consists of 46 chromosomes which then can be paired into 23 pairs. 22 pairs of chromosomes are similar in both males and females which are commonly known as autosomes. However, the 22nd chromosomes (X and Y) are different as these are the sex chromosomes. The human cell can divide in two ways: Meiosis, in which the number of…
