Nucleus
Function:The nucleus is usually located around the center of the cell connected to the endoplasmic reticulum as part of the endomembrane system. The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains DNA (in chromosomes). The nucleus is surrounded by the nuclear membrane. ribosome small organelles composed of
RNArich cytoplasmic granules that are sites of protein synthesis.It nucleus includes the: nucleolus, chromatin, and the nuclear envelope which have a variety of other functions. Relation to protein synthesis: nucleus produces the sequence of amino acids that form a protein, the DNA in the nucleus undergoes some processes like translation and transcription through which the sequence is formed and finally create the proteins Physical description:The nucleus regulates the synthesis of proteins in the cytoplasm through the use of messenger RNA (mRNA). Messenger RNA is a transcribed DNA segment that serves as a template for protein production.

Nucleolus
The nucleolus is a round body located inside the nucleus of a eukaryotic cell. It is not surrounded by a membrane, but sits in the nucleus. The nucleolus makes ribosomal subunits from proteins and ribosomal RNA (rRNA). It then sends the subunits out to the rest of the cell where they combine into complete ribosomes. Function: The nucleolus makes ribosomal subunits from proteins and ribosomal RNA (rRNA).
It then sends the subunits out to the rest of the cell where they combine into complete ribosomes. Relation to protein synthesis: Ribosomes that are created by the nucleolus are a site of protein
synthesis.
