BIOL 102 Lecture 10: March 9th Notes
Document Summary
Study tip: writing out what teacher says is more efficient than typing on a computer. Nettie maria stevens: discovered that male beetles produce two types of sperm. Gene expression: each cell in your body (except sperm/egg) has the same dna. Cells express different genes based on their functions. Production of rbgh gene: coded by a specific bgh gene, transfer of the bgh gene to bacteria allows growth under ideal conditions. Cloning makes many copies of the same gene. Restriction enzymes: act like highly specific molecular scissors to cut dna at specific sequences. Plasmid small circular piece of dna that exists separate from the bacterial chromosome. Answer: cows treated with rbgh may suffer from more infections. Artificial selection has been happening for thousands of years. Includes about 85% of u. s. corn and soy. Processed foods contain gm products: corn syrup, soy, vegetable oils.
