Question

Quizplus · Accepted Answer

The correct order from largest scale to smallest scale is chromosome (largest structural unit), genetic map (based on genetic linkage information), physical map (based on direct DNA analysis), overlapping clones (sets of cloned DNA fragments that overlap each other), and nucleotide sequence (the most detailed level, showing the exact order of nucleotides).
