The recombinant DNA \(segments of DNA from two sources that have been combined in vitro and transferred to cells in which their information can be expressed\), carrying the gene of interest, is then placed into a rapidly multiplying cell that quickly produces many copies of the gene. The final harvest may consist of large amounts of the gene product or many copies of the gene itself.
Choose the correct option.
The recombinant DNA purpose for genetic engineering is to _______

  • make a great number of copies of the gene of interest.
  • destroy a lot of copies of the gene of interest.
  • study all the copies of the gene of interest.
  • change numerous copies of the gene of interest.
