The article consider the two sub-processes of nucleic acid detection separately from one another. It mentions sample preparation for the detection of nucleic acids consists of isolating and purifying the target nucleic acids, after the cells have been ruptured or lipoprotein envelopes have been removed, it is necessary to remove the cell debris and other foreign substances that interfere with the subsequent amplification process and to purify the nucleic acids before the second process step.
