Polymerase chain reaction (PCR) amplifies specific DNA sequences by cycling through
- A
Transcription (mRNA synthesis), processing (capping and splicing), translation (protein synthesis)
- B
Restriction (enzyme cutting), ligation (joining fragments), transformation (uptake by bacteria)
- Ccheck_circle
Denaturation (heat), annealing (primers bind), extension (Taq polymerase synthesizes)
- D
Initiation (origin recognition), elongation (DNA synthesis), termination (telomere capping)
Explanation
Each cycle doubles the target DNA. Taq polymerase from thermophilic bacteria survives the high-temperature denaturation step.
