Is chromatin in the nucleus or cytoplasm?

The nucleus stores chromatin (DNA plus proteins) in a gel-like substance called the nucleoplasm. The nucleolus is a condensed region of chromatin where ribosome synthesis occurs. The boundary of the nucleus is called the nuclear envelope.

Is chromatin found in cytoplasm?

The prokaryotic genome typically exists in the form of a circular chromosome located in the cytoplasm. … Chromosomes are made up of a DNA-protein complex called chromatin that is organized into subunits called nucleosomes.

Is chromatin in the nucleus?

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped around nuclear proteins in order to fit inside the nucleus. Chromatin exists in two forms.

Are chromosomes in the nucleus or cytoplasm?

In prokaryotes, the circular chromosome is contained in the cytoplasm in an area called the nucleoid. In contrast, in eukaryotes, all of the cell’s chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones.

Is cytoplasm an organelle?

Cytoplasm is not a cell organelle. It is simply a generic term that describes everything within the plasma membrane and outside of the nucleus. We typically think of cell organelles as being within the cells.

Does chromatin have RNA?

Whether RNA itself plays a direct structural role in chromatin is, however, not known. Here, we report results indicating that RNA plays a general structural role in eukaryotic chromatin. Our results indicate that purified chromatin contains significant amounts of RNA (2%–5% of total nucleic acids).
