Answer 2

Explanation:

The nucleolus is a distinct structure in the nucleus of the cell composed of filamentous and granular material. It is the site of synthesis and processing of ribosomal RNA and the assembly of this RNA with ribosomal proteins into ribosomal subunits. Ribosomes are the molecular machines that in the cytoplasm translate mRNA into protein molecules. In the electron microscope, the nucleolus consists of a darker fibrillar (pars fibrosa) and granulated (pars granulosa) matrix interspersed with lighter areas. The pars fibrosa consists of the heavily transcribed rRNA genes and rRNA. The pars granulosa contains the maturing ribosomal precursor particles. The lighter areas are filled apparently with nontranscribed DNA
