What does “PCR” actually mean in Biotechnology - Principles and Processes, and why does it matter for NEET?
amplifies DNA in a tube using primers, dNTPs and heat-stable Taq polymerase across denaturation-annealing-extension cycles.
In simple words: amplifies DNA in a tube using primers, dNTPs and heat-stable Taq polymerase across denaturation-annealing-extension cycles. Getting PCR clear matters because NEET questions on Biotechnology - Principles and Processes usually test this idea directly, not just a formula you memorised.
Key point
PCR
Common mistake
thinking PCR needs living cells to copy DNA.
Memory tip
PCR copies DNA in a test tube with Taq polymerase -- no cells involved.
