Detailed explanation-1: -The prokaryotic DNA is found in a coiled loop floating in the cytoplasm, whereas the eukaryotic DNA is found inside the nucleus.
Detailed explanation-2: -Prokaryotic organisms are single-celled organisms that lack a cell nucleus, and their DNA therefore floats freely in the cell cytoplasm.
Detailed explanation-3: -The DNA/genetic material will be freely floating in the cell cytoplasm. These are primitive cells which lack most of the cell organelles (e.g. mitochondria, Endoplasmic reticulum etc.) The prokaryotic cells consist of bacteria, blue-green algae, mycoplasma and PPLO (Pleuro Pneumonia Like Organisms).
Detailed explanation-4: -Their cellular components float freely within the cytoplasm, although their DNA is clustered within a region called the nucleoid. Inside the cytoplasm, many prokaryotes have small, circular, double-stranded pieces of DNA called plasmids.
Detailed explanation-5: -Prokaryotic cells comprise bacteria and archaea. Their genetic material isn’t stored within a membrane-bound nucleus. Instead, it is stored in a nucleoid that floats in the cell’s cytoplasm.
