NURSING ANM AND GNM

Detailed explanation-1: -Experimental evidence suggests that the nucleoid is largely composed of about 60% DNA, plus a small amount of RNA and protein. The latter two constituents are likely to be mainly messenger RNA and the transcription factor proteins found regulating the bacterial genome.

Detailed explanation-2: -The bacterial genome is present in the cell within a complex structure, the nucleoid. The nucleoid contains the genomic DNA, and molecules of RNA and proteins.

Detailed explanation-3: -It is found in bacteria and some plants. C is correct. The nucleoid is not enclosed by a membrane and therefore has immediate contact with the surrounding cytoplasm.

Detailed explanation-4: -The nucleoid (meaning nucleus-like) is an irregularly shaped region within the prokaryotic cell that contains all or most of the genetic material. The chromosome of a typical prokaryote is circular, and its length is very large compared to the cell dimensions, so it needs to be compacted in order to fit.

Detailed explanation-5: -In bacteria well-defined nucleus is absent. Genetic material is not enveloped by a nuclear membrane. Therefore, nucleoid represents the genetic material in which single condensed, coiled, double-stranded DNA molecule is present. So, the correct option is ‘True’.
