Assignment 1: Biology Article Cinthya Jacobo Professor: Dr. Francie Coblentz Introduction to Biology: SCI115 11/08/2015 The article “Therapeutic Cloning, and stem cell Research” by Gena Smith is about how we can extract stem cells from replicated human embryos and use them for medical and therapeutic purposes. The stems cells are perfect because they are what the article calls “master cells” which with the help of science, can be manipulated to become anything from brain cells to kidney cells

eugenics. Genetic engineering was incorporated in certain species of plants to modify crop yields and improve resistance to certain crop diseases. The scientists inserted a given gene into plasmid bacteria to ensure that the plant cell assumed the new DNA. The technology has allowed many plant species to thrive in harsh conditions, including cold, hot, and effectively resist pests. There are different edible foods, which have been designed through the technology. The last century has recorded discoveries

2.2.1- Outline the differences between reproductive and non-reproductive cloning Reproductive Cloning: production of offspring which are genetically identical to the mother or the other offspring Non- Reproductive Cloning: Use of stem cells in order to generate replacement cells, tissues and organs which may be used to treat particular diseases 2.2.2- Describe the production of natural clones in plants using the example of vegetative propagation in elm trees Vegetative Propagation: The production

Gene therapy fact sheet 1. What is a gene therapy? * Gene therapy is an experimental way of using genes to treat or prevent disease. * Gene therapy is an experimental technique for treating disease by altering the patient's genetic material. Most often, gene therapy works by introducing a healthy copy of a defective gene into the patient's cells. 2. Methodology of gene therapy In general, genetic material cannot be inserted directly into a person's cells. Instead, it is delivered

Genetic engineering (GE) refers to the technique of modification or manipulation of genes (the biological material or chemical blue print that determines a living organism’s traits) from one organism to another thus giving bacteria, plants, and animals, new features. The technique of selecting the best seed or the best traits of plants has been around for centuries. Humans have learned to graft (fuse) and hybridize (cross breed) plants, creating dwarfs and other useful forms since at least 1000 B

The theory of Endosymbiosis explains the origin of chloroplasts and mitochondria and their double membranes. This concept assumes that chloroplasts and mitochondria are the result of years of evolution initiated by the endocytosis of bacteria and blue-green algae. According to this theory, blue green algae and bacteria were not digested; they became symbiotic instead. Endocytosis is when a substance gains entry into a cell without passing through its cell membrane. A cell's plasma membrane encloses

Discuss the nature /nurture debate in relation to the development of an individual In this article there will be a discussion of nature and nurture debate in relation to the development of an individual. Nature is genetic and biological influences and nurture is a social, economic and environmental influence as stated by Stretch B and Whitehouse M (2010) Every person is unique. Everyone is biologically different from every other human being. Personâs characteristics are features of the

experiments. Watson in DNA: The Secret of Life talks about the steps that scientists do: from making observations and hypotheses to constructing experiments and drawing conclusion, he quoted the example of Mendel and Walter Sutton, where they observed the special phenomenon of the colors of peas from parent to offspring, and could found out that different alleles can be passed on to the next generation after experiments. In Watson’s own experiment of investigating the DNA structure, Watson also

Review Biology Test #1 Chapter 3: Water and life • Polar covalent bonds in water result in Hydrogen bonding between the molecules. These bonds give water its special properties • In presence of water, ionic bonds are weak and covalent bonds are strong. Without water, ionic bonds are stronger. • Each water molecule can make 4 hydrogen bonds. • Water properties: 1. Polarity 2. Surface tension 3. Cohesion 4. Adhesion 5. Capilarity 6. High specific heat 7. Heat bank 8. Heat of vaporization
