EVERYDAY SCIENCE

Detailed explanation-1: -Prokaryotic cells do not have a nucleus. Instead, their DNA floats around inside the cell. Organisms with prokaryotic cells are called prokaryotes.

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. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-3: -Prokaryotes are small and lack membrane-bound nuclei 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.

Detailed explanation-4: -In organisms such as humans, DNA is organised into structures called chromosomes inside a nucleus, a membrane-bound compartment within each cell. Bacteria lack a nucleus, and how bacterial DNA is organised has puzzled biologists for many years.

Detailed explanation-5: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
