MCQ IN MEDICINE

Detailed explanation-1: -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 in their cytoplasm.

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: -All the prokaryotic organisms lack membrane-bound organelles and a well-defined nucleus. Since bacteria are prokaryotic organisms, they do not have a nucleus.

Detailed explanation-4: -Bacteria, of course, have no nucleus and therefore also nuclear membrane. genetic information-DNA is organized into numerous chromosomes and is packaged in the nucleus. The nucleus is bounded by a membrane mRNA, tRNA and rRNA are made in the nucleus and shipped out into the cytoplasm.

Detailed explanation-5: -They help in replication as well as carry genetic material. In prokaryotes, the DNA is arranged in the irregular-shaped region known as the nucleoid. Hence we can say that the prokaryotes can survive without a nucleus.
