Answer:
increasing extension time
Explanation:
The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.
The CNS involves the brain and spinal cord and the PNS involves the body nerves.
The correct answer should be <span>d. hypertrophic obesity</span>
However, a more correct answer would be a combination of C and D because the hypertrophic type is when obesity occurs due to an increase in the size while hyperplastic is when their number increases. Since it's only mentioned here as hyperplasia, only hypertrophic should be the answer.
