The nucleolus is a distinct region within the cell nucleus, primarily responsible for the production of ribosomes, which are essential for protein synthesis.
It houses genes that encode ribosomal RNA (rRNA), a key component of ribosomes. The nucleolus plays a role in assembling ribosomal subunits, which then combine in the cytoplasm to form functional ribosomes.
These ribosomes facilitate the translation of genetic information from messenger RNA (mRNA) into proteins. The nucleolus also participates in various cellular processes, including cell cycle regulation, stress responses, and the assembly of other ribonucleoprotein complexes. Its function is integral to protein synthesis and overall cell function.
