Role of Nucleolus in Production of Ribosomes | Genetics

In his article we will discuss about the role of nucleolus in production of  ribosomes (explained with diagram). The nucleolus is the site for rRNA transcription and processing as well as for assembly of ribosomal subunits. The nucleolus is organised at the nucleolus organising regions (NORs) of some chromosomes. These chromosomal regions contain the genes for 5.8S, 18S and 28S [...]

Nucleolus: Structure and Functions | Eukaryotic Cell

In this article we will discuss about the structure and functions of nucleolus. Structure of Nucleolus: Estable and Sotelo (1951) described the structure of a nucleolus under the light microscope. According to them, nucleolus consists of a continuous coiled filament called the nucleolonema embedded in a homogenous matrix, the pars amorpha. The first description of nucleolar ultra structure was given [...]
