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.
This study was performed to help teenagers in school learn about the make-up of DNA. DNA is the genetic material of any living organism and is found inside the cells of the organism. There are videos on the internet on how to do this. Also there are also chapters in science textbooks on how to do this. Some existing knowledge is that when all of the solutions are mixed together in the test tube they will separate into three layers one consisting of the strawberry puree (lysis solution), another is the DNA precipitate, and the last is the actual DNA.
What is the benefit of the modification? Because the GM tomatoes can remain fresh longer they have time to ripen in the sun before picking, resulting in a better tasting tomato! 4. Three advantages of genetically modified foods Longer lasting foods can be more easily transported, Having extra vitamins in food help poor people from becoming malnourished or going blind, and the insecticides inside some genetically modified plants keep farmers from having to spray the whole place down with toxic wastes, and they also 5. A counter argument to one of the disadvantages of genetically modified food Some antibiotics can be transferred to humans and make it harder for us to fight infections, genetically modifying foods could potentially put farmers out of work, and some important insects could be at risk because of the insecticides in foods.

The agent which the new genetic material is incorporated into is the bacterial plasmid. A plasmid is a circular deoxyribonucleic acid (DNA) molecule that replicates independently of the bacterial chromosome and often is the avenue for which a bacteria gains resistance to an antibiotic. Recombinant plasmids are those which have DNA from two or more sources incorporated into a single plasmid. To make recombinant plasmids, two different plasmids are cut with the same restriction enzyme: this restriction enzyme only cuts at particular restriction sites, so the type of cut it makes in one plasmid will be the same type of cut in another plasmid. The cut must produce “sticky ends” so that the plasmid DNA can bind to any
Purpose In this lab we are trying to get a broader understanding of the transformation of bacteria by exposing them to pBLU plasmids. Introduction Transformation is the manipulation of a bacterial cell's DNA in order to alter the cell's genotype or phenotype by absorbing free DNA from its surroundings. This can result in a nonpathogenic bacteria becoming pathogenic by absorbing the DNA of a broken open or dead pathogenic bacteria. In our case it is taking in the pBLU plasmid. A plasmid is a spherical self-replicating DNA molecule that is not actually a part of the bacterial cell but can integrate itself into the bacterial chromosome.
What is the function of the cytoskeleton? To give the cell shape 12. What is inside nucleus that is responsible for providing the cell with its characteristics?

Use the information to answer the questions.
Examine your living organism and determine if it is a bacteria, achaean or a eukaryote. At each step in classification, check the requirements for each category to determine where the species belongs. You then would begin to ask yourself a series of questions about the organism one question will lead to another. If the organism cannot be identified through the questions you will than need to do a gram staining process. You will look at the bacteria through a microscope exposing the bacteria's cell wall to two types of stains: a violet and a red one.
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.
