You have discovered a very small amount of DNA from an ancient organism that you want to save and study.What is the very first thing you should do to allow you to study this DNA in the lab?
A)RT-PCR
B)Gel electrophoresis
C)Polymerase chain reaction (PCR)
D)Insert the DNA into a vector

Polymerase chain reaction (PCR) is the best choice to amplify the small amount of DNA recovered from an ancient organism. PCR will allow for the creation of multiple copies of the DNA, making it easier to work with in the lab. Gel electrophoresis will separate DNA fragments based on size, but it cannot amplify the DNA. RT-PCR is used to amplify RNA, not DNA. Inserting the DNA into a vector would be a later step in the process, after the DNA has been amplified.
