Question

You are studying a new gene "X" that you think controls skin color in Bearded Dragons. In order to determine what gene X does you need lots of gene X DNA to work with. So, you decide to amplify it through the process known as PCR. You have a forward and a reverse primer that have been designed to gene Xf – a gene in frogs that is similar to the one found in the Bearded Dragon. You are pretty sure that these two primers will work in Bearded Dragons, so you decide to go ahead with the PCR. In frogs, the Forward Xf primer binds gene Xf between nucleotides 32 and 47. The Reverse Xf primer binds between nucleotides 1110 and 1135. What size PCR product would these two primers create if they amplified the frog gene Xfp

Answer 1

The correct answer is - 1103 bp.

Step-by-step explanation:

PCR or polymerase chain reaction is a process that uses a primer to amplifying the desired segments of DNA molecules. It is a technique that can amplify a million copies of the DNA segment.

given:

forward primer binds from - 32 to 47

reverse primer binds from - 1135 to 1110

PCR product would be between - 32 to 1135

So, product size would = 1135-32 = 1103.

Thus, the correct answer is - 1103.
