What is the primary function of the CFTR protein?

PCR

has specific applications in research, forensic, and clinical laboratories,

including the following (select the most accurate answer):

In your experiment, you added forward and reverse primers to your PCR reactions. These primers contained RNA sequences that were antiparallel and complementary to CFTR DNA sequences.

Which of the following is not used in a process involving Taq DNA polymerase?

How many DNA duplexes are obtained from one DNA duplex after 3 cycles of PCR? 

The DNA sample loaded into the wells of this gel will migrate according to its size.  

Four lanes are numbered on the gel below. (A lane is a corridor through which DNA passes as it leaves a well.)

In what phase of meiosis is this cell?

What phase of mitosis is this cell in?

Is this statement True or False? Watson-Crick base pairing between purines involves colinear N, H and O

atoms with proper donor and acceptor atoms, which ensures that each base pair has the same 2-nm width no matter what

the sequence is.
