Meiosis

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…

The operations of cloning have brought out an abundance of fundamental milestones laying concrete on rearing onto the likelihood for an acceptance of therapeutic cloning. There exists a manifold quantity for the, “applications of this technology in nonhuman animal models will undoubtedly contribute in a major way to vaccine development and the unraveling of teratological and genetic problems in human development as well as impacting wildlife conservation efforts” (Wolf, Meng, Ely, & Stouffer,…

Down Syndrome is the most prevalent and recognizable chromosomal abnormality in live born children, with a current prevalence of 2.8 out of 1000 children born with the genetic disorder [1]. In 1866, John Langdon Down termed the condition “mongolism” before it was later termed Down syndrome in honor of his discovery. Nearly a century later, geneticists Jerome Lejeune and Patricia Jacobs reported the chromosomal abnormality for the first time in humans to be secondary to a trisomy of chromosome 21…

College students focus on the content presented to the in their courses like understanding the difference between mitosis and meiosis or what exactly Plato meant in his writings. Rarely do students take the time to step back from their studies and analyze the organization of their classes and how that may affect their performance in the course. It is extremely interesting to get a chance to look back on the courses I have taken and analyze their culture rather than content. I will be looking…

house” of the cell and this is how eukaryotic cells has been created. Human body is composed of about 70 trillion of eukaryotic cells which starts with a fertilization of a female’s egg and male’s sperm. From the replication of the single cell called meiosis, a human is being created. However, no one knows which cell or cell group will become what part of the fetus’s body. Those cells are called stem cells. According to Ciram.ca.gov the stem cells…

Abstract This experiment was constructed to distinguish the differences with Prokaryotes and Eukaryotes by growing through a variety of media. These media consisted of rich and minimal. Rich media is a media that contains an abundant supply of nutrients for bacteria to grow. Minimal media is a media that contains the minimal amount of nutrients for bacteria to grow. Medias are important because they not only are used in growing microorganisms but are used in the medical field to help with the…

The person could have an extra chromosome (Klinefelter syndrome, Trisomy X, Down syndrome, etc.) or they lack a chromosome (Turner syndrome). Aneuploids are believed to be the result of some form of error that occurs during meiosis. This error generally causes a chromosome not to separate, which is called a nondisjunction. Gametes that have extra chromosomes unite with regular chromosome which results in a trisomy. A trisomy chromosome is one that, instead of being diploid,…

Intro: A. Alkaloids are the most diverse group of natural products that exist within living organisms (Hartmann, 1998). Alkaloids are a diverse group of low molecular weight; nitrogen-containing compounds mainly derived from amino acids, and are found in about 20% of plant species. Alkaloids play a very important role in organism metabolism and functional activity. They are metabolic products in plants, animals and microorganisms (Aniszewski, 2007). Due to their potent biological activity, many…

With natural selection its major driving mechanism, evolution is the change over time in the makeup of genetics of a population. Supported by evidence from many scientific methods, Charles Darwin, in On the Origin of Species, asserts that inheritable variations occur in individuals in a population. In the process known as natural selection, due to competition for limited resources, individuals with more favorable characteristics or phenotypes are more likely to survive and better reproduce,…

DOWN SYNDROME: A LIFE-LONG DISORDER Imagine facing two choices: parents having to abort their unborn baby, or they go through the pregnancy knowing their child is going to have Down syndrome, knowing that raising him or her will not be easy. Many parents face this choice everyday. According to Peggy Parks, author of Down Syndrome, 80 to 90 percent of unborn babies diagnosed with Down syndrome are aborted (19). Everyday, all around the world babies are diagnosed with Down syndrome and parents…
