Cell cycle

in breast cancer stem cells through E113, the Wnt-beta catenin signaling pathways and the tumor regulator p53? I. Introduction: To explain the cellular and molecular features of my focus question I will provide background on cancer stem cells, some of the various signaling pathways and breast cancer specifically. A. Cancer Stem Cells (Tumor-initiating cells) 1. Basic Features: Have the capacity to self renew and the ability to produce multiple distinct differentiated cell types, which are…

chromatin condensation and cell preparatory phase of division. The following phases take place in this process: gap 1 phase (G1) (cells grow/synthesize proteins required for mitosis activating the cell’s metabolism to break down carbohydrates/lipids transforming food into energy, this phase chromosomes consist of only one DNA molecule), S phase (replicates the cells DNA by copying the DNA molecules of each chromosome gaining 2 chromatids), and gap 2 phase (G2) (the cell grows/synthesizing more…

Worksheet 1 1. How would you explain the cell cycle to your patient? (20 points) Scenario: A 21-yearl-old lady came into the primary care network clinic to avail of health teachings and resources for first time mothers. After graduation from nursing school, Alisha Marston got married to her former classmate and now expecting a baby due in 7 months. After being given instructions for the blood work and necessary health teachings, I offered to further discuss how the fertilized egg in her body…

from this tragic disease. The World Health Organization states that in the year of 2030, this statistic will grow to 21.4 and 13.2 million respectively (Fanghua, 2010, p.297). But, what is cancer. Cancer is a disease caused by non-stop division of cells and it can happen almost anywhere in the human body. People who are stricken with this disease are people who are loved and will be missed when they inevitably die. They are willing to endure the pain and suffering for the smallest chance of…

Sensitivity of Cancerous C.elegans with Mitochondria Dysfunction Mitophagy is a selective autophagic elimination of damaged or excessive mitochondria, especially when cells are under adverse stress. Mitophagy has been identified as the cause of various human diseases and even cancer. In recent years, researchers gradually regard mitophagy as the target for cancer treatment, although the role of mitophagy in the developmental and metabolic process of cancer is still not clear. In this…

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…

Cell Cycle and Cancer By Samuel Lehew Cell Cycle and Cancer By Samuel Lehew (Rough Draft) The cell cycle is a complex set of stages where the cell duplicates itself, in which the captivating process of this is explained cancer will also be explained and how the different types of cancer can be treated differently. Also, the fatality rates and the genetic inheritability. Cancer can affect any at any moment, just one mistake in one of these stages and the mutation and uncontrolled cell growth…

Meiosis is the dividing of cells as the embryo develops in the womb, as stated in the Pearson Anatomy & Physiology edition 10. It starts the haploid division of gametes that further develops the embryo into a fetus and then into a fully functional baby within nine months. This form of cell replication creates four daughter cells that have only half of the amount of chromosomes that are contained within a human body, 23 instead of 46. Within the book it explains that meiosis goes through…

Meiosis is the process in which a diploid cell is divided into 4 haploid cells. Meiosis is separated into two parts meiosis I and meiosis II. In meiosis I, the first step is interphase and in this phase DNA is replicated. For example, in the diagram the DNA of big A, small a, big B, small b will all be replicated. This will create a doubling of the DNA that existed and will later be condensed into chromosomes. After interphase, prophase I occurs; in prophase I the replicated chromosomes pair up…

two diploid cells are formed at the end of it. It results in two daughter cells with the same number of chromosomes. Mitosis has interphase, prophase, metaphase, anaphase, and telophase. In interphase, the chromosomes have already been replicated. In interphase, chromosomes duplicate. During prophase, spindle fibers attach at each centromere. In metaphase, the chromosomes line…
