WebA nucleolus is built by a nucleolus organizing region (NOR) of a specific chromosome. These regions contain the genes for ribosomal RNA subunits that build the protein synthesis machinery. Since in a diploid human cell, in total 10 chromosomes containing NORs exist, in principal 10 nucleoli per nucleus could be present. WebApr 9, 2024 · The nucleolus is an area within the nucleus that is involved in the assembly of ribosomal subunits. Genes located along the DNA are transcribed into RNA molecules, primarily messenger RNA (mRNA), transfer RNA (tRNA, and ribosomal RNA (rRNA). Messenger RNA is then translated into protein at the ribosomes. gino\u0027s downtown chicago https://craftedbyconor.com
