LIFE SCIENCE

Detailed explanation-1: -Prokaryotic cells, such as bacteria, have a free-floating chromosome that is usually circular and is not enclosed in a nuclear membrane . Instead, the DNA simply exists in a region of the cell called the nucleoid.

Detailed explanation-2: -Prokaryotes: Prokaryotes are cells without a nucleus. They have genetic materials but are not enclosed within a membrane.

Detailed explanation-3: -These membrane-bound structures are called organelles. In eukaryotes, the cell’s genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.

Detailed explanation-4: -DNA is the genetic material of a prokaryotic cell. Since there is no cell nucleus in prokaryotic cell DNA is attached to the cell membrane and in direct contact with the cytoplasm.
