prokaryotes do not contain DNA

Explanation:
Detailed explanation-1: -The cell membrane is bound to DNA and is in close contact with the cytoplasm. There is no enclosing membrane, because there is no actual nucleus, but merely a concentration of DNA called a nucleoid. Therefore, prokaryotes can live without a nucleus.
Detailed explanation-2: -Prokaryotic cells differ from eukaryotic cells in that they lack any membrane-bound organelles, including a nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.
