2. PCR amplification of the TAS2R38 gene a. The number of copies of the 303 bp sequence grows exponentially (1-2-4-8-etc) after each cycle. The number of cycles we used is on page 97. What is the number of copies of the 303 bp fragment that will theoretically be present at the end of our reaction? b. Denaturation of the 303 bp segment of the TAS2R38 gene is a critical first step in the PCR perties of a DNA segment that...
