Question

question 1 1 pts you are attempting to see if a suspect is associated with a crime. the only evidence you have is a tiny drop of blood from the crime scene, which is not enough to run an analysis. how can you increase your crime scene dna sample? you can use gel electrophoresis to determine the length of the dna found in the sample. you can collect dna from everyone who was near the crime scene. you can use pcr to increase the amount of dna. you can use restriction enzymes to cut the dna sample into multiple copies.

Explanation:

PCR (Polymerase Chain Reaction) is a technique used to amplify (increase the amount of) DNA. Gel electrophoresis is for separating DNA fragments by size, not increasing DNA amount. Collecting DNA from everyone near the crime scene doesn't increase the amount of the crime - scene DNA sample. Restriction enzymes cut DNA at specific sequences, they don't make multiple copies (increase the amount) of the DNA sample.

Answer:

You can use PCR to increase the amount of DNA.
