Question

Question 3 (5 points) Saved In eukaryotes nucleosomes are universal structural components of chromatin. In prokaryotes (bacteria) DNA forms nucleoids which consist of? o a) a naked circular DNA molecule associated with NAP's (nucleoid- associated proteins), transcription factors and mRNA (messenger RNA) a naked circular DNA molecule aggregated with transcription factors and mRNAs. b) o) naked DNA associated with chromatin forming proteins HU, H-NS, d) a single naked circular DNA molecule. Fis, CbpA and Dps. g.

Answer 1

Option-A) a naked circular DNA molecule associated with NAP's (nucleoid- associated proteins), transcription factors and mRNA (messenger RNA)

Step-by-step explanation:

The genetic material in the eukaryotes is packaged as nucleosomes which are enclosed in a double membrane organelle called nucleus whereas in prokaryotes the genetic material is enclosed in a nucleus like structure called nucleoid which is formed by the condensation of protein and RNA into a circular structure.

Since the genetic material is not enclosed by any membrane, therefore, the nucleoid or genetically material is considered to be free floating in the cell.

The genetic material of the Bacteria contains the nucleoid-associated proteins which are similar to the histone proteins of the eukaryotes and also constitute the protein part of the nucleoid.

Thus, option-A is the correct answer,
