Biology 115 Name: Russell Tapia Homework 1 Use your book, lecture notes and the Internet to complete the homework assignments. You will submit this assignment as a PDF or docx file. Biotechnology 1. List and describe some of the major areas of biotechnology. • Transgenic Biotechnology = the splicing of DNA from one species to another • Reproductive Cloning = the production of mammals through cloning • Cell Reprogramming = the production of needed cell types through the reprogramming of genomes • Forensic Biotechnology = The use of biotechnology to stablish identities of criminals/crime victims and so forth 2. What is the difference between therapeutic and reproductive cloning? Reproductive cloning is making a complete genetic copy of a mammal Therapeutic cloning would be more likely used for humans and would be restricted to creation of organ replacement or limb replacement. 3. What is SCNT? Describe how biotechnologists perform it. Diagram it here. Somatic cell nuclear transfer = a means of cloning mammals through fusion of one somatic with an egg cell whose nucleus has been removed. I. Remove nucleus from egg cell Egg cell III. Let develop II. Fuse enucleated egg cell with adult cell Adult cell 3. How are restriction enzymes and PCR important to biotechnology? 4. With Restriction enzymes it allows for cutting DNA at a predictable location and PCR makes replication of DNA efficient. Biotechnology in the News! – CRISPR Check out the links provided in this week’s module. 1. What is CRISPR? Allows scientist to make specific changes to specific genes in living cells 2. What does CRISPR make possible in the world of Biotechnology? Gene editing 3. Why is CRISPER controversial? Because there are people that will want to use them for selfish reason like designer babies or making mutant species on purpose, lets call it playing god.
