If a PCR-amplified sample hybridizes with two allele specific probes one normal and one mutant sequence a carrier may be identified ifA. Both probes give a signalB. Neither sample gives a signalC. Only the mutant probe gives a signalD. None of the choices are correct

The Correct Answer is A "Both probes give a signal"

Explanation:

the transformed and the ordinary one – are utilized in a similar response and through the opposition that emerges between them for tempering on the objective DNA succession, the authoritative of the splendidly coordinated preliminary to the format is firmly preferred comparative with the groundwork varying by a solitary base.  

Just one converse preliminary is utilized in a serious oligopriming PCR, to serve amalgamation with both allele-explicit groundwork's, which along these lines must get from the equivalent – inverse of that of the opposite groundwork – strand of DNA succession. One all things considered can define a serious PCR, in which the serious oligoprimers are of inverse bearing, however this requires the utilization of two converse preliminaries, as well, and most likely expand improvement strategies.  

In COP PCR each of the three preliminaries, to be specific the two forward introductions for the transformation site, one (m) and the other (wt) and the basic converse preliminary, are utilized in one response with a given layout DNA

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
