Question

Nucleoid is the single circular strand of DNA duplex. Explain?

Answer 1

Nucleoid represents the genetic material of the prokaryotes. Nucleoid is also known as genophore, prochromosome, incipient nucleus and chromoneme.

Unlike the eukaryotic (true) cells, bacteria do not have a membrane enclosed nucleus. The chromosome, a single, continuous strand of DNA, is localized, but not contained, in a region of the cell called the nucleoid. All the other cellular components are scattered throughout the cytoplasm. Nucleoid consists of a single circular strand of DNA duplex which is supercoiled.
