clone by the processes of artificial twinning and somatic cell nuclear transfer. While organisms such as hydras and coral use budding which is when a new organism grows off the body of the parent organism naturally until the new organism falls off and begins to fend for itself. The earliest form of artificial cloning began in 1885 with sea urchins. The cloning of the sea urchins was both a clone and a refutation of a current theory of cell biology. Scientists posited that the first combination…

Animal Cloning As new technology is developed, cloning becomes a higher discussed topic. Cloning is the process of producing similar populations of genetically identical individuals. Cloning has been seen a as a recent discovery but cloning has been happening in nature since the beginning of time. Common animals that clone naturally are starfish, bacteria, and even some plants. But cloning becomes a controversial topic when humans artificially make clones of animals that normally reproduce…

this is just the thing for you this tells you everything you need to know and more? This was interesting because who knew you could actually grow bacteria that’s awesome and the problem is, which bacteria will grow the most on a TV remote or on a cell phone? All of these source information’s talk about facts about bacteria and they explain some things they use and what they are needed for and they show what bacteria can do in different places. “Bacteria is neither plant or animal,…

humans yet, but they are getting closer to cloning humans year after year. Scientists have already cloned human stem cells in 2013 by Shoukhrat Mitalipov and his team at Oregon National Primate Research Center. From a technical perspective, cloning humans and other primates is more difficult than in other mammals. It is more challenging because the cells require proteins essential to cell division. Also, multiple copies of an ancestor’s genes might bring several surprises. When critics say human…

Embryonic Stem Cell Research (ESCR), therapeutic, and reproductive which both fall under Somatic Cell Nuclear Transfer (SCNT). Embryonic stem cells are stem cells derived from the identical inner mass cells of a human embryo. The researching…

Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used to…

Cells have specific structures within them that allow them to carry out their functions; these structures are called organelles. Organelles have different functions within a cell that is called Division of Labor. They are also classified in two different groups, membranous and non-membranous. Membranous organelles are surrounded by a membrane while of course, non-membranous are not surrounded by a membrane. When describing the organelles and their function, first will be the membranous…

Nucleus The Nucleus is an example of a command centre found inside a eukaryotic cell; it’s usually the most prominent organelle, yet it occupies only 10% of the total volume of the cell. If this cell did not have a Nucleus, it would be defined as a prokaryote cell, however if the Nucleus was damaged and not repaired, the cell would simply die. The cell nucleus is enclosed within a double membrane (contains an Inner and Outer Nuclear Membrane) called the Nuclear Envelope, which separates the…

This can provide information about the way proteins move through cells, interact with other proteins, and implement their effects inside living cells (Stretton et al., 1998; Scott et al., 1998). Flow cytometry, specifically FACS when dealing with GFP tagged proteins, is a way to measure and sort proteins and molecules from a mixed biological sample based on…

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…
