often only small amounts of dna are found at a crime scene. which technique uses an enzyme to replicate dna regions from a small sample of dna for use in dna fingerprinting?\nvtrs (variable tandem repeats)\npcr (polymerase chain reaction) analysis\nstrs (short tandem repeats)\nmtdna (mitochondrial dna) analysis

Answer

Brief Explanations:

PCR uses DNA - polymerase enzyme to amplify (replicate) specific DNA regions from a small sample of DNA for various applications including DNA fingerprinting. VNTRs and STRs are types of DNA markers, not replication techniques. mtDNA analysis is for analyzing mitochondrial DNA, not a replication technique for general DNA fingerprinting.

Answer:

B. PCR (polymerase chain reaction) analysis
