Detailed explanation-1: -Prokaryotes are a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and archaea.

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: -Assertion :The true nucleus is generally absent in prokaryotes. Reason: An undifferentiated, unorganised fibrillar nucleus is observed in prokaryotic cells.

Detailed explanation-4: -Bacteria are prokaryotes. A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid. So, bacteria have DNA.
