which of the following about prokaryotic chromosomes is true? a. comprise at least two chromosomes b. are made of DNA wrapped tightly around histone proteins c. include histone and nonhistone proteins d. consists of a circular DNA molecule I have doubt that the answer can possibly be (b) and (d)
OpenStudy (abhisar):
A prokaryotic cell is basically represented by bacteria. They lack a well defined nucleus, have no nuclear membrane. The genetic material is basically naked i.e no histone proteins are present. The DNA is circular in shape.
OpenStudy (javk):
like you said it can't be `b` because, DNA's in prokaryotic cells aren't coiled. It would be worth mentioning at this point that the job of the histones is to assist in the tightly coiled formation, said, therefore, histones are not found in prokaryotic cells
