MCQ
The correct sequence of different steps of polymerase chain reaction is:
- AAnnealing denaturation extension
- BDenaturation extension annealing
- CDenaturation annealing extension
- DExtension denaturation annealing
Explanation:
Polymerase chain reaction is a technique used to replicate a fragment of DNA so as to produce many copies of a particular DNA sequence. A single PCR amplification cycle involves three basic steps: denaturation, annealing and extension (polymerisation).
