Mitosis

Pathophysiology: Cells in the body go through a natural state of mitosis where they replicate copies of themselves. Once a cell realizes there isn’t any more room for growing or sees a defect in itself, the cell goes through apoptosis (cell death). However, there are instances where a cell doesn’t recognize it has a defect or mutation and it starts to affect the shape of the cell. Once this mutated cell starts mitosis, it will regenerate a lot of undifferentiated cells, which turn into a…

organisms would cease to exist. Like all living things, the cell must also reproduce and eventually die. Cells reproduce through a series of division called mitosis, and also through a nuclear division called meiosis which produces two separate cells that only contain half of the genes found in the mother cell. Within the body most cells use mitosis to divide and reproduce.…

The three stages are: Interphase (which uses the most time of the cell cycle), mitosis and cytokinesis. A beta cell goes through each stage in order to repair the damaged cells and replace them with genetically identical cells in the pancreatic tissue. Interphase, the first stage of the cell cycle, has three phases which are the following:…

ribbon, a pot of boiling water, a prokaryote, a chromosome, a pedigree, and a factory to represent human impact, a flower to represent photosynthesis, a food chain, an energy pyramid, an embryo, humans evolving, a biomolecules chart, and the phases of mitosis. I drew a breast cancer ribbon because we talked about different types of cancer. There are many factors that go into the diagnosis of cancer. A lot of the cancers have the same risk factors, such a nutrition and smoking. Family history…

Tongue cancer is a very common cancer that plagues people daily. It is a form of oral cancer that forms in the front two-thirds of the mouth. It usually develops in the squamous cells of the mouth. Around forty- three- thousand people in the U.S alone are affected by this type of cancer just this year. It kills roughly one person per hour, which is twenty-four in one day alone. This cancer causes a lot of deaths and a little more than half of the people with this cancer will die in the next five…

Chromosomes When the DNA copies, it condenses into chromosomes, two chromosomes are put together to make sister chromatids. The narrow part of the chromatids are the centromeres, this is where they are most closely attached. Phases of the Cell Cycle Mitosis This is the shortest part of the cell cycle. Interphase This takes up 90% of the cell cycle, this is when the cell grows bigger and gets “fat and sassy” and copies the…

Interruptions in the Cell Cycle The cell cycle is the process of which a somatic or gametic cell reproduces DNA and splits into two or four different cells, respectively. This process contains multiple stages such as G1, S, G2, Mitosis or Meiosis, and Cytokinesis. Throughout this procedure, many errors can occur and be harmful to the organism. To prevent these mistakes from becoming a problem, the cell cycle contains many checkpoints and regulators (Lodish). A checkpoint is where “stop and…

phase is where the cell grows and carries out metabolic processes. S, the synthesis phase where the cell replication of its DNA occurs. G2, the gap 2 phase is where the cell continues to grow making preparations for the second major process: M, the mitosis. G0 phase is where the cell, which temporarily stops dividing or has totally terminated dividing rests.

in which the number of chromosomes is halved, producing four gametes. This type of cell division is required for the production of egg and sperm cells for sexual reproduction. The other type of cell division is Mitosis which occurs when more cells are needed. Through the process of mitosis two identical cells which are also the same as the parent cell are produced. Many errors can occur during both types of cell division causing complications within the human body. During the process of…

because they need to learn how a reduction in chromosomes is very critical. Without it the two gametes during fertilization, the offspring would result in with two times the regular number of chromosomes. Scientist use models to demonstrate mitosis one, mitosis two, meiosis one, and meiosis two. A model is a three-dimensional representation of a person or a thing. Models help scientist to understand and explain certain concepts or processes. When explaining the process meiosis, it…
