The technique called fluorescence in situ hybridization (FISH)uses
A)stains to sort chromosomes into general size classes,designated A through G.
B)DNA probes with attached fluorescent molecules that indicate specific DNA sequences.
C)lures to pull out specific sequences from their chromosomes.
D)stains that distinguish AT-rich from GC-rich sequences.

Question

Quizplus · Accepted Answer

FISH uses DNA probes with attached fluorescent molecules to indicate specific DNA sequences. This allows for the visualization of the location of specific genes or regions on chromosomes. FISH does not sort chromosomes into general size classes or distinguish between AT-rich and GC-rich sequences, as described in options A and D. FISH also does not use lures to pull out specific sequences from their chromosomes, as described in option C.
