Practice Question 1:<\/strong>Design a recombinant DNA molecule using PCR (Polymerase Chain Reaction) and restriction enzymes. A researcher wants to clone a gene into a plasmid vector. The gene is 1000 bp long and has XbaI <\/em>and SacI <\/em>restriction sites at its ends. The plasmid vector has XbaI <\/em>and SacI <\/em>sites within its multiple cloning site. The researcher performs PCR to amplify the gene, then digests both the gene and plasmid with XbaI <\/em>and SacI<\/em>. The gene is then ligated into the plasmid, and the recombinant DNA molecule is transformed into E. coli <\/em>bacteria.<\/p>\n\n- What is the purpose of using restriction enzymes in this experiment?<\/li>\n
