DNA Amplification is done in: (A) PCR, (B) NASBA (Nucleic acid sequential based amplification), (C) Ligase chain reactions, (D) DNA sequencing
Answer is A. PCR is an in-vitro DNA amplification procedure in which millions of copies of pariticular sequence of DNA can br produced within a few hoursTwo DNA primers about 20-30 nucleotides with complementary sequence of the flanking region can be synthesized
