You are asked to study a new species,and you are presented with a miniscule amount of DNA from that species.If you do not find a way to increase the volume of the DNA sample,you will not be able to work with the sample at all.Which technique should you use to increase the amount of DNA in the sample?

PCR (Polymerase Chain Reaction) allows for the amplification of a small amount of DNA, creating millions of copies of the target DNA sequence. This would allow for enough DNA to work with in further analysis. Electrophoresis separates DNA fragments based on size, DNA fragmentation breaks DNA into smaller pieces, and cladistics is a method for classifying organisms based on evolutionary relationships and would not be useful for increasing the volume of DNA.
