Answer: Amplify specific DNA sequences.
- A Determine the exact sequence of bases in DNA
- B Amplify specific DNA sequences
- C Synthesize new proteins from an mRNA template
- D Deliberately create new mutations in target genes
Correct answer: B. Amplify specific DNA sequences
Explanation: PCR amplifies (copies) a specific DNA sequence millions of times. Used in forensics, medical diagnosis, and research.
Recombinant DNA technology: a gene of interest and plasmid are cut by the same restriction enzyme, ligated into a recombinant plasmid, and introduced into a host cell.
Concept context
Recombinant DNA, GMOs, PCR, CRISPR, and biotechnology applications. Growing importance in NEET.
