Name 4 examples of genetically modified crops. Pesticide resistant rape plants, Insecticide sweet corn, golden rice which contains large amounts of vitamin A, Long-lasting tomatoes 4. Which genetically modified foods are sold now and where are they grown? Soya Beans, Sweet Corn,
1-2-09 Glowing Bacteria Genes are pieces of DNA which hold the instructions for making proteins. The protein will then give an organism a particular trait. Genetic transformation means changes caused by genes, and requires the insertion of a gene into an organism, in order to change the trait. this technique is used by in many areas of biotechnology. Agriculturally, plants can be genetically transformed to be resistant to pesticides, spoilage, and frost.

Hybridization- crossing different traits to bring the best of organisms into one. For example crossing disease resistance of one plant with the food-producing capacity of another to produce a superior plant. 3)Cloning is the process of taking a single cell from an adult organism to recreate another genetically identical organism. 4)DNA fingerprinting is developed by molecular biology; it analyzes unique sections made up of a variety of DNA band. DNA fingerprinting is a powerful and crucial tool that can determine a person’s identity.
To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating (. DNA has a double helix structure and has two strands running in opposite directions (UIC, 2013). 2. How does an organism’s genotype determine its phenotype? Genotype determines the genetic makeup of an individual organism.
stores proteins and alot of exporting (sending stuff out of the cell) 3. In which part of the cell would you expect to find nucleotides? building block for DNA, DNA found in the nucleus 4. Name the two organelles involved in energy conversion.chloroplast and mitochondria 5. What are the basic functions of the organelles in chapter 4?
I. Title: pGLO Transformation Lab II. Purpose; We want to be able to observe, comprehend and analyze genetic transformation as we genetically alter organisms. III. Hypothesis: If bacteria with + pGLO plasmids that are resistant to the antibiotic ampicillin and have the gene for GFP, colonies with survive and grow on the transformation plates that have LB/ amp.
What kinds of clinical specimens may yield a mixed flora in bacterial cultures? Oral, Skin, or GI specimens 5. When more than one colony type appears in pure culture, what are the most likely sources of extraneous contamination? Individual colonies can be picked up on the inoculating loop, or straight wire and inoculated in to the fresh agar or brother media References Cowan, M. K. (2012).

There are many models of enzymes, such as the lock and key model, which explores the structure of the enzyme and its ability to bind with a substrate molecule which is specific and complementary. There is also the induced fit model which explored the ability of enzyme molecules to change shape slightly enabling it to fit and bind to substrate molecules which must be complementary and specific. The importance of enzyme and substrate molecules to fit together, is the formation of the products which may enable many vital reactions to occur within cells and organisms. Enzymes are in important in digestion and the replication of DNA. Within digestion lactose within milk is broken down by the enzyme lactase, without lactose having a complimentary specific shape to it lactase enzyme, some people are lactose intolerant.
