Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bacteria are prokaryotes which means they
A
have a nucleus on their capsule
B
do not contain a nucleus
C
can live in environments with and without oxygen
D
None of the above
Explanation: 

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: -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 are considered to be prokaryotes, which means they do not have a nucleus and other membrane-bound organelles. Instead, the DNA is found in the nuceloid, a region with no membrane, or as a plasmid, a small circle of extra genetic information, floating right in the cytoplasm, the fluid that fills the cell.

Detailed explanation-5: -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. locomotion-rigid flagella.
