NEET BIOLOGY

Detailed explanation-1: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes. The nucleolus is also where ribosomal RNA genes are transcribed.

Detailed explanation-2: -An area inside the nucleus of a cell that is made up of RNA and proteins and is where ribosomes are made. Ribosomes help link amino acids together to form proteins. The nucleolus is a cell organelle.

Detailed explanation-3: -The nucleolus is found only in plant cells.

Detailed explanation-4: -The nucleolus is the largest nuclear organelle and is the primary site of ribosome subunit biogenesis in eukaryotic cells. It is assembled around arrays of ribosomal DNA genes, forming specific chromosomal features known as nucleolar organizing regions (NORs) which are the sites of ribosomal DNA transcription.

Detailed explanation-5: -The nucleolus is an organelle in the nucleus that plays a key role in the transcription and processing of ribosomal RNA (rRNA).
