Question

Do bacteria have circular DNA?

Answer 1

Bacteria:

1. These are simple unicellular organisms that lack a well-defined nucleus and other membrane-bound organelles.
2. Bacteria and archaea belong to prokaryotes.
3. Escherichia coli, Pseudomonas, Staphylococcus, Lactobacillus, etc are some examples of bacteria.
4. Most bacteria have double-stranded circular DNA as their genetic material.
5. This circular DNA is suspended in the cytoplasm with other proteins as a distinct structure called the nucleoid.
6. Some may have more than one circular DNA and some bacteria like Streptomyces have linear double-stranded DNA.
