Detailed explanation-2: -From the above information we know that bacteria are prokaryotes so they do not have a true nucleus. Therefore the given statement is false.
Detailed explanation-3: -The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell.
