Detailed explanation-1: -Bacteria are prokaryotes. A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid. So, bacteria have DNA in their cytoplasm.
Detailed explanation-2: -Bacteria cells do not have a nucleus that houses their DNA. However, they do have other structures that are made up of DNA called nucleoids and plasmids. Bacteria cells have multiple structures that help them function.
Detailed explanation-3: -Like other organisms, bacteria use double-stranded DNA as their genetic material. However, bacteria organise their DNA differently to more complex organisms. Bacteria have a single circular chromosome that is located in the cytoplasm in a structure called the nucleoid.
Detailed explanation-4: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
