NEET BIOLOGY

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 are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages.

Detailed explanation-3: -Bacteria are prokaryotes, lacking well-defined nuclei and membrane-bound organelles, and with chromosomes composed of a single closed DNA circle.

Detailed explanation-4: -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-5: -Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles.
