FISH and Microarrays Both Use Probes to Hybridize to Sequences

question 52

Multiple Choice

FISH and microarrays both use probes to hybridize to sequences of the pathogen genome.  They differ in that ________.

• A)FISH involves adding fluorescently labeled probes directly to a patient's sample,whereas microarrays involve the attachment of thousands of potential gene sequences from pathogens to an absorbent plate and adding DNA from the patient's sample to it,allowing matching sequences to hybridize
• B)microarrays involve adding fluorescently labeled probes directly to a patient's sample,whereas FISH involves the attachment of thousands of potential gene sequences from pathogens to an absorbent plate and adding DNA from the patient's sample to it,allowing matching sequences to hybridize
• C)FISH involves scanning and analyzing the pathogen genome multiple times,whereas microarrays involve separating DNA samples into fragments using restriction enzymes,then exposing the fragments to varying voltage levels from three different directions
• D)microarrays involve scanning and analyzing the pathogen genome multiple times,whereas FISH involves separating DNA samples into fragments using restriction enzymes,then exposing the fragments to varying voltage levels from three different directions
