Q
State 5 points that sum up PCR
A
- PCR is a technique by which any sequence of DNA can be cloned or amplified
- There are no need for cloning vectors, or transformation of bacterial cells followed by screening programme
- DNA is amplified entirely in vitro, in an automated system involving a thermocycler
- PCR is rapid and selective that can produce billions of coies of DNA sequences in a few hours.
- This is much faster than the time taken for transformation of bacteria.
