Answer:
My best guess would be boil it!
I would say the results of the experiment but not the hypothesis, if we're saying possible corrections to the hypothesis count as something outside of it
I'd guess B. I'm not 100% sure though, so if you don't want to chose B...
A would be the best other option, in my opinion
Answer:
Polymerase chain reaction (PCR)
Explanation:
Polymerase chain reaction (PCR) is a method by which a target DNA fragment is amplified to produce millions of copies. In PCR, the Taq polymerase enzyme uses nucleotides and primers to replicate a small DNA segment <em>in vitro</em> and produces two DNA molecules. The newly formed DNA molecules are denatured by heating to facilitate their replication to produce four double-stranded DNA molecules. In this way, the number of DNA molecules is doubled in each cycle. Therefore, the small amount of DNA obtained from the minuscule spot of blood on a murder suspect’s shirt can be amplified using PCR.
