Intro to Biotechnology Mark Muller March 19, 2015 Chelsea Claverie Midterm Study Guide The Northern Blot detects the presence of certain RNA sequences, while the Southern blot can detect various DNA segments. Northern blot uses a gel electrophoresis, blot, RNA probes, and x-ray to determine the presence of a particular mRNA sequence that was immobilized and run in the electrophoresis. Southern blot uses an autoradiograph in combination with an electrophoresis gel to identify similarities between DNA. Similar DNA should travel the same distance in the electrophoresis, on the blot, and have the same binding sites from probes on the autoradiograph.

Genetic Technology Applied Genetics Selective Breeding Selective breeding is the breeding of organisms to produce certain desired traits in their offspring In selective breeding, a genome is changed slowly and deliberately, over many generations. Selective breeding is one example of biotechnology. Biotechnology is the use of living organisms to make products, such as medicines and improved crops, or to benefit humans. Ancient peoples native to North and South America used selective breeding to develop corn and potatoes from wild plants. Today, farmers still use selective breeding to develop new crops. In order for a new breed with a desired trait to be established, only the offspring that inherit the desired trait are selected to reproduce.

Campbell's Biology, 9e (Reece et al.) Chapter 20 Biotechnology The new questions in Chapter 20 cover all of the chapter?s concepts and are primarily at the higher skill levels. In addition, the chapter presents several scenarios that are accompanied by a series of questions. Multiple-Choice Questions 1) Assume that you are trying to insert a gene into a plasmid. Someone gives you a preparation of genomic DNA that has been cut with restriction enzyme X. The gene you wish to insert has sites on both ends for cutting by restriction enzyme Y. You have a plasmid with a single site for Y, but not for X. Your strategy should be to A) insert the fragments cut with restriction enzyme X directly into the plasmid without cutting the plasmid.
