True or False. The circular single chromosome that most prokaryotes possess is simply floating around in the cytoplasm.
False. Nothing as important as a chromosome is left to chance! Prokaryotic chromosomes may not be enclosed in a nucleus, but they are carefully packaged and anchored in place by a primitive cytoskeleton. The location of the chromosome is called the nucleoid.
