Gordoncillo Professor Vacura BIO 101 – Lab 31 October 2014 Cell Division Mitosis Abstract Mitosis and Meiosis: Cells can be divided in unicellular organisms or in multi-cellular organisms. DNA controls the cell division. Bacteria reproduce by a process called binary fission. Bacteria have one chromosome that’s attached to the cell membrane. The chromosome replicates and the two copies separate as the cell grows. Over a period of time this one cell makes two cells. Eukaryotes do the process of mitosis

INTRODUCTION Embryonic stem cell research and medication is a controversial topic that best displays the battle between ethics and science. Stem cells can bring new possibilities to medicine and biology by understanding how diseases form‚ and affect the body. With this research new cures could be made. The controversy is over whether or not itś ethical to use these embryonic stem cells because they have the potential to become a human being. Using Embryonic stem cells will bring more good than evil

of mitotic cell division‚ meiosis‚ and fertilization in the human life cycle. Mitosis allows for growth and repair from the fertilized egg to the adult. In reproductively mature individuals‚ meiosis creates gametes with half the genetic material. The male gamete then fertilizes the female gamete during sexual reproduction‚ forming a zygote with a full set of genetic material. 2. Why are both cell division and apoptosis necessary for the development of an organism? Cell division is needed

through 3 successive days: First Day: Trypan Blue cell viability assay: Description Trypan blue staining is a simple way to evaluate cell membrane integrity (and thus assume cell proliferation or death) but the method is not sensitive and cannot be adapted for high through put screening. Short 96 well assay: EACH condition should be done in triplicate or more. Steps 1. Trypsinize one T-25 flask and add 5 ml of complete media to trypsinized cells. Centrifuge in a sterile 15 ml falcon tube at 500

The Ethics of Stem Cell Research By Aly Beall English 102 F Professor Stott 11 December 2012 Aly Beall ENG 102 F Professor Stott Due Date: December 11‚ 2012 The Ethics of Stem Cell Research Stem Cells are unspecified cells that have the capability to renew themselves through cell division. They can be made to become tissue or organ specified cells; for example they can be turned into muscle cells‚ red blood cells‚ or even brain cells. There is much disagreement on the ethics

Cell division consists of two processes: mitosis and cytokinesis. Mitosis— division of the nucleus and its chromosomes— is divided into five phases:prophase‚ prometaphase‚ metaphase‚ anaphase‚ and telophase. Mitosis is followed by cytokinesis‚ when the cytoplasm splits to form two separate daughter cells. The cytoplasm of a cell in late interphase contains two centrosomes‚ each of which may contain a pair of centrioles. In the nucleus‚ the chromosomeshave been replicated during S phase‚ but are

Cellulitis: Cellulitis is a common skin infection caused by bacteria. Causes Staphylococcus and streptococcus bacteria are the most common causes of cellulitis. The skin normally has many types of bacteria living on it. When there is a break in the skin‚ however‚ bacteria can enter the body and cause infection and inflammation. The skin tissues in the infected area become red‚ hot‚ irritated‚ and painful. Risk factors for cellulitis include: • Cracks or peeling skin between the
