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.
According to the text, which of the statements is TRUE?

• In fact, the gene of interest is able to create its copies in the recombinant molecules of DNA.
• According to the final result, the recombinant molecules of DNA might stay unchanged.
• As a result, an amount of the recombinant molecules of DNA can change.
• No doubt, the amount of the recombinant molecules of DNA can be constant.
