Microbiology - Bacteria Morphology - Discussion

Option A is the right answer.

I think option A should be the answer. The prokaryotes don't have a nucleus but they have a structure that looks like a nucleus (nucleoid) containing the genetic material. Chromatin is present in eukaryotes.

Option A should be the correct answer.

Chromatin is a complex of macromolecules found in cells, consisting of DNA, protein, and RNA. The primary functions of chromatin are 1) to package DNA into a more compact, denser shape, 2) to reinforce the DNA macromolecule to allow mitosis, 3) to prevent DNA damage, and 4) to control gene expression and DNA replication. The primary protein components of chromatin are histones that compact the DNA. Chromatin is only found in eukaryotic cells (cells with defined nuclei). Prokaryotic cells have a different organization of their DNA (the prokaryotic chromosome equivalent is called genophore and is localized within the nucleoid region).

Chromatin is absent in Prokaryotic cells. It is a combination of DNA and some proteins (majorly histones).

Prokaryotes have nucleiod(nucleus like) but have no nucleus which is a membrane bound organelle.

Prokaryotes have not nucleoid.

Nucleoid, chromatin and nuclear material are synonymous.
