Which of the Following Tools of Genetic Engineering is Used

Question

Which of the following tools of genetic engineering is used to make multiple copies of DNA?
A)PCR
B)Gel electrophoresis
C)Reverse transcription
D)Recombinant DNA

Accepted Answer

PCR (polymerase chain reaction) is a tool used to make multiple copies of a specific segment of DNA. This method involves repeatedly heating and cooling the DNA to separate and replicate the strands, thus amplifying the amount of DNA available for further analysis or manipulation.
