Once dna is collected at a crime scene, it must be processed in the lab. if there is a limited quantity of dna available, what step must the technician take in this process?

PCR is used to amplify the DNA.

Explanation:

PCR is acronym for polymerase Chain Reaction, a molecular biology procedure for amplifying segments of DNA, through the production multiple copies with the aid of the enzyme DNA polymerase under controlled factors. In PCR, thermal cycling or the continuous heating and cooling of the sample for DNA melting and replication is employed.

In this case, Once DNA is collected at a crime scene, it must be processed in the lab. But the DNA obtained was of limited quantity therefore it is advisable for the technician to amplify the DNA using PCR.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.

explanation:
