उत्तर
Yes, detection of disease before its symptoms appear can be possible by only amplifying the nucleic acids by the technique known as Polymerase Chain Reaction (PCR), which was not possible with conventional diagnostic tests. A single DNA molecule can be copied endlessly using Primers, DNA polymerase enzyme, and free nucleotides under appropriate conditions in PCR.
