Question

How does the nucleus relate to its function?

Answer 1

Hint: The nucleus is a specialized organelle that functions as the memory processing center and the administrative body of the cell. This organelle has two primary roles: it preserves the genetic contents (or DNA) of the cell, and regulates the activity of the organization.

Complete answer:
The nucleus consists of the double membrane envelope that protects the entire organelle intact, isolating its ingredients from the rest of the cell, as well as the Nucleo skeleton that protects cells as a whole. The nucleus ensures the protection of the genes and manages the functions of the entire cell by manipulating gene expression. That's why the nucleus is termed the control core, or "brain". The nucleus is the location of genetic transcription, thus retaining it distinct from the cytoplasm. It means that gene expression is actually occurring in eukaryotic cells that have a nucleus, and that this gene regulation isn't really applicable to prokaryotes. This suggests that the entire purpose of the nucleus is to guide gene expression and stimulate DNA replication during the cell cycle. Since membrane proteins could not get into the nucleus through the nuclear membrane, small holes called nuclear pores dot the layer of the envelope. Such pores control the transportation of these molecules by carrier proteins embedded in the double surface of the membrane. That being said, small molecules and ions are able to move through the membrane. The main functions of the nucleus inside the cell include replication of nucleic acids and further genetic regulation during cell division. Transcription and further post-transcription processing of pre-messaging ribonucleic acids (mRNAs) happen within the nucleus and mature mRNAs are moved to the cytoplasm where translational events take place. Thus, the nucleus includes system compartmentalization inside the cell, allowing for better levels of gene management.

Note:
The nucleus is highly biocompatible and also has the ability to withstand deformation. In addition, the nucleus interacts continuously with the surrounding cytoskeleton. Several nuclear subdivisions or nuclear bodies correspond to the mechanical support and functional organization of the nucleus. This promotes numerous biochemical processes, in specific gene expression.
