D) genome mapping
E) microarray or PCR

Question

Quizplus · Accepted Answer

Microarrays and PCR (Polymerase Chain Reaction) are both techniques used to detect the presence of specific genetic sequences, such as those of a virus, in a sample. Microarrays can simultaneously detect the presence of many genes by hybridizing the sample to known sequences on a chip. PCR amplifies a specific DNA sequence, making it possible to detect even small amounts of viral DNA.
