Question

Quizplus · Accepted Answer

DNA analysis can distinguish between high-GC Gram-positive bacteria (which have a high percentage of guanine and cytosine in their DNA) and low-GC Gram-positive bacteria (which have a low percentage of guanine and cytosine in their DNA). Gram staining, cell shape, and metabolic pathways cannot reliably distinguish between these types of bacteria.
