PCR Question: after 25 cycles in the thermometer, the DNA template is amplified to _____ copies....
A fragment of DNA is amplified from a single molecule of template DNA for 22 cycles. Theoretically, how many PCR products will be produced?. Assume exponential amplification starts with cycle 1. please explain and how would the answer be different if only one primer was used?
Today we amplified 50 ng of Bos taurus (calf) DNA by PCR. This amount of DNA contains about 15,000 molecules of the insulin gene [50 ng DNA= 2.5 x 10-20mol; (2.5x10-20)x(6.023×1023) = 1.5 x 104molecules]. We performed PCR for 35 cycles to amplify the amount of this gene. a. What is the theoretical fold amount of DNA amplified by 35 cycles of PCR (remember the 2Nformula)? b. How many molecules of the insulin gene would, therefore, be present after PCR?
• 4. How many copies of the primers do you add to the PCR? You add 3 pl. of a 5 M solution of each primer, If you had 100 copies of the template DNA would there be enough primers to support 30 cycles of PCR? Remember the amount of template doubles (in theory) with each cycle. After 1 cycle there will be 2xthe starting amount, after 2 cycles 4 x the starting amount.
Suppose you start a PCR reaction with 3 copies of a double stranded DNA fragment. How many copies will be present after 4 replication cycles? a. 7 b. 64 c. 48 d. 24 e. 8
In PCR, how is the segment of DNA that is to be amplified determined? A. By the activity of the polymerase B. By the extension of the annealed primers C. By using primers that flank the target sequence D. By denaturation of the entire genome

Q1 The immediate template for PCR amplification is double stranded DNA. (True or False) Q2 A primer is a DNA oligonucleotide. (True or False) Q1 Denaturation of DNA double helix takes place at 96 C. (True or False) Q2 A primer is a single stranded DNA oligonucleotide. (True or False) Q1 16 doubled stranded DNA fragments are obtained from one DNA double stranded template after 4 cycles of PCR. (True or False) Q2 Denaturation of DNA double helix takes place...
if you start with 2 pieces of DNA, after 4 cycles of PCR how many would you have?
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...
