Detailed explanation-1: -The nucleolus is a ribosome production factory, designed to fulfill the need for large-scale production of rRNAs and assembly of the ribosomal subunits.

Detailed explanation-2: -The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.

Detailed explanation-3: -The nucleolus is the site of ribosomal RNA synthesis, processing and ribosome maturation. Various small ribonucleoproteins also undergo maturation in the nucleolus, involving RNA modification and RNA-protein assembly.

Detailed explanation-4: -The nucleolus is also where ribosomal RNA genes are transcribed. Once assembled, ribosomes are transported to the cell cytoplasm, where they serve as the sites for protein synthesis.

Detailed explanation-5: -The nucleolus is the region of the nucleus that is engaged in ribosome synthesis. The nucleolus contains genes encoding ribosomal RNA, newly synthesized ribosomal RNA, and ribosomal proteins.
