English 111 November 13‚ 2013 Stem Cells A Better Future for Tomorrow The field of human genetics has been a “hot topic” since the 1950’s when James Watson and Francis Crick first discovered the basic structure of DNA (“Human Genetics”). Stem cells are found in humans and animals that have distinctive properties. They are the building blocks of life simply put. They have the ability to divide and reproduce themselves for a long period at a time. Stem cell research is a very controversial topic

Stem Cells Stem Cells are fundamentally cell templates. These cell templates are used to create all the cells in our body. Stem cells under the right circumstances are manipulated into other cells‚ such as mussel cells and liver cells. The thing that makes stem cells so useful is that not only can they become almost any cell in your body but they also have the special characteristics to be able to self re-new or multiplying while still keeping the potential to become useful cells for our body

Define Stem Cells and give background information on them. Stem cells are a class of undifferentiated cells that are able to differentiate into special cell types. There are two types of Stem Cells: Adult Stem cells and embryonic stem cells. Embryonic stem cells come from embryos that are 3-5 days old. They are often taken from the umbilical cord. They are used more than adult stem cells. Adult stem cells mainly come from bone marrow. Their primary function is to maintain homeostasis by replacing

Prokaryotic cells are single celled organisms that were formed at the formation of the earth‚ so are the most basic life forms. The prokaryotes are organised in the ‘three domain system’ and include bacteria and blue-green algae. Prokaryotes live in many environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals. This is a diagram of a prokaryote cell and it shows that they are not very complex cells. They do not contain any membrane

between animal and plant cells. Although plant and animal cells both have mitochondria‚ cytoplasm‚ and ribosomes they differ in many ways. Animal cells do not have a cell wall and are round with irregular shapes. Centrioles are also present in all animal cells‚ as well as most eukaryotic cells. Plant cells only have centrioles if they are in the lower plant species. Both types of cells have vacuoles‚ but their functions are quite different. The purpose of vacuoles in a plant cell is to store water and

To do so‚ it is essential to

Biology Period 1 Stem Cell Debate I think that we should stick to researching adult stem cells because it is more ethical‚ better success rate than embryonic cells‚ and they are more knowledgeable to the people. Adult stem cells are controversial but way less than embryonic stem cells. Stem cells are found in all multicellular organisms and are divided through mitosis. Adult stem cells are found in various tissues. Adult stem cells can be regenerated into specialized cells just not as many. Embryonic

Suddenly‚ stem cells are everywhere. Once relegated to the depths of esoteric health journals‚ the microscopic clusters have made their way to the nation�s front pages. The complexity and drama surrounding these relatively simple cells has increased due a ticking clock: By the end of the month‚ President Bush is scheduled to decide whether to continue federal funding for stem cell research. The question of using stem cells for research is intrinsically scientific‚ and yet has become the political
