Structure and Function of the Cell Nucleus

Nucellus in Interface

Presents nuclear envelope and developed chromatin fibers. The core has a very active K and occurs for later transcription translation. Also, before division occurs, DNA duplication takes place. We also find the nucleoplasm and the nucleolus or nucleoli. When the nucleus is in division, it presents some major changes. The condensed chromatin fibers give rise to structures called chromosomes. Then, the nuclear envelope will also change. In this way, the chromosomes remain immersed
