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.
B is the correct answer due to the fact that applied sciences means adding to already developed technology there scientist are creating another drug to cure human diseases by mixing different elements through the process of an experiment
all membrane bound organelles are absent in prokaryotic cells. They only have a membrane, cytoplasm, DNA and ribosomes(and also some sort of a cytoskeleton that helps with division and cell shape)
Hope this helps
Can you provide more of the question so I can answer it?
