Question

question 26
when researchers wish to make multiple copies of a section of dna outside of the cell, they employ the
o copy machine
o pepsin activation reaction
o polymerase chain reaction (pcr)
o centrifuge
1 pts

Explanation:

PCR (Polymerase Chain Reaction) is a technique used to amplify (make multiple copies of) a specific section of DNA. A centrifuge is used to separate components of a mixture based on density. Pepsin activation reaction is related to the activation of the enzyme pepsin (involved in protein digestion). A copy machine is a general - purpose device for copying documents, not for DNA replication.

Answer:

Polymerase chain reaction (PCR)
