Andrew Platt Tuesday Lab @ 3:30 General Biology I Laboratory Eight Pre-lab Questions 1. What is electrophoresis? Briefly describe how the process works. A way of separating large molecules. It uses an electrical field to separate DNA molecules through electrical force based on the DNA molecules size. 2. What is a DNA fingerprint? How does it work? When a probe is made for DNA that is repetitive, it often detects a large number of fragments. These fragments are often not identical in different individuals. We say that the population in polymorphic for these molecular markers. These markers are the DNA fingerprint. 3. Define autosomal and recessive as the terms relate to hereditary diseases.

Unformatted text preview: Autosomal means that the disease is not favorable to one sex, there are an equal number of copies of the chromosome in males and females. Recessive alleles are an allele that produces its characteristic phenotype only when its paired allele is identical. 4. Briefly describe "recombinant DNA." Provide some examples of how this technology has contributed to health? Genetically engineered DNA made by recombining fragments of DNA from different organisms. Production of vaccines against communicable diseases. Subunit uses antibodies. DNA vaccines not dependent on antibodies, dependent on second arm of bodys immune defense....
