What does a nucleoid consist of?

Answer 1

CompositionExperimental evidence suggests that the nucleoid is largely composed of DNA, about 60%, with 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. Proteins helping to maintain the supercoiled structure of the nucleic acid are known as nucleoid proteinsor nucleoid-associated proteins and are distinct from histones of eukaryotic nuclei. In contrast to histones, the DNA-binding proteins of the nucleoid do not form nucleosomes, in which DNA is wrapped around a protein core. Instead, these proteins often use other mechanisms to promote compaction such as DNA bending or DNA-DNA bridging.

Nucleoplasm can be defined as one of the types of protoplasm. It contains (nucleus sap) or karyplasm. It is a highly sticky liquid that surrounds the chromosomes and nucleoli.
