Three bаbies hаve been bоrn аt the lоcal hоspital. These babies were mistakenly placed in the nursery without any identifying nametags, and now you don’t know which baby goes with which couple! You decide to perform DNA fingerprinting in order to match each baby with the right couple. A) DNA fingerprinting relies on identification of microsatellites, or SSR’s. Define SSRs, and state how SSR alleles differ from each other. B) In DNA fingerprinting, SSR’s are amplified using PCR. What does “PCR” stand for? C) After completing the PCR, you separate the products using gel electrophoresis. Your results are shown below. Which Baby goes with which couple? Briefly explain how you determined the answer. D) Which bands on the gel are the largest? Which are the smallest?
