Cell Nucleus

3D Model

Cell Nucleus with nuclear pores, outer membrane, inner membrane, nucleolus, chromatin and RNA leaving the nucleus via the nuclear pores. The nucleus is a usually round-shaped organelle of the eukaryotic cellcontains the cell’s DNA, and is surrounded by a double membrane called the nuclear envelope. Chromatin is a DNA / protein complex in eukaryotic cells allowing packaging long DNA molecules into compact, dense structures. Understanding chromatin structure and its contribution to gene regulation is the subject of epigenetics. The nucleolus is the largest structure in the nucleus of eukaryotic cells, where ribosome biogenesis takes place. Messenger ribonucleic acid (mRNA), a single-stranded molecule of RNA stems from transcription from genes of the chromatines, leaves the nucleus and is read by ribosome during protein synthesizing. The shell, the chromatins, the nucleolus and the RNA are each selectable groups in the obj file.
