case of cloning is with Dolly the Sheep, which was the first animal to be cloned from a somatic cell. With cloning comes a wide variety of potential for science, some of which include organ transplantations and reproductive uses. The latter is what will be focused on in this paper. Reproductive cloning is the process of creating an animal that is genetically similar to the donor animal through somatic cell nuclear transfer. This is the same process

Adrenoleukodystophy (ALD) Understanding an Animal Cell: Basic Units of Life The cell is the fundament unit of life. They make up the smallest level of a living organism in the human body, where the metabolic processes happen to in order to maintain life. It itself is considered a mini-organism made up from organs called organelles. These organelles are the structural and functional units and are created from several macromolecules connected together. A typical animal cell contains the following organelles (Tracey

of the 21st chromosome in every cell. In medical terms “trisomy” refers to having an extra copy of a chromosome. The proper name for down syndrome is Trisomy 21 because of the extra copy of the 21st chromosome ("Facts about Down Syndrome”). Mosaicism occurs when a child is born with an extra chromosome in some but not all of their cells. Mosaicism normally has less severe symptoms than trisomy 21. Translocation down syndrome occurs

cloning it is the whole genetic of a single individual. There are different methods to do with this type of cloning but the most common is somatic cell nuclear transfer. The first step is to remove the nucleus from the mother egg. Second is to take a somatic cell from the individual being cloned, take out the DNA and put it in the egg of the mother. Then the cell that is formed from putting the two together is then induced to divide and form an embryo.

Calculus formation happens in a sequence of three steps including pellicle formation, biofilm formation, and mineralization. The first step in calculus formation is the development of a pellicle. A pellicle is an organic substance made of mucoproteins that quickly forms within minutes of being detached from the tooth surface. The next step is biofilm maturation where the biofilm forms in layers. Microorganisms grow and colonize on the growing pellicle. There are many morphologic forms of bacteria

Imagine cloning a cell 37.2 trillion times until there’s a whole person. Today, scientist have come extremely close to making this possible. Scientist haven’t been able to clone an adult human yet, but some have managed to successfully been able to clone a human embryo. Cloning will allow people to increase the amount of livestock and crops key to mankind’s survival, cure who knows how many diseases and even bring people back to life from a simple DNA cell. But even though all these things could

controversial field of science that involves the introduction of human embryonic stem (hES) cells or human neural stem cells into nonhuman animals, thus creating a human-animal interspecific chimera. With the promise of significantly enhancing health and possibly curing some of the most deadly diseases, humankind has mitigated diverse ethical issues associated with stem cell research. However, the use of human stem cells to create chimeras has generated unusual ethical dilemmas, in particular, whether or

the degradation of the extracellular matrix, which promotes excessive immune cell leakage to inflammation sites and enhances organ damage. The roles of most cystatins are not clearly defined or known; however, these proteins have been found to have secondary functions. For example, as stated in this article by Eaves-Pyles in 2013, cystatins C and B have were found to have anti-tumor effects that decreased the rapid cell growth and metastasis of a tumor. Along with this function, Cystatin C has

into individual cells in a Petri dish. These embryos are placed in a surrogate mother for their development and are identical because they all had the same fertilized egg. The other method of entire organism cloning is called somatic cell nuclear transfer or SCNT. SCNT involves isolating a somatic cell, or any cell that is not a reproductive cell, and removing the nucleus and DNA from an egg cell. The nucleus is then transferred from the somatic cell to the egg cell. Now, the egg cell with a new nucleus

Observing Cells George Meni Introduction Did you ever wonder what makes up all living things? Organisms are in most living things, there is a range of organisms from unicellular to multicellular organisms that are inside a human, dog, cat, plant or any living growing thing. An example of a unicellular organism would be; Bacteria, Archaea, Protozoa. An example of a multicellular organism is; most types of Fungi, Algae. There are also organisms that are partly unicellular and multicellular like:
