A spherical structure is observed within the nucleus. It is not membrane-bound and its content is continuous with the rest of the nucleoplasm. Which of the following is the primary cellular process that occurs within this structure?

Step-by-step solution

According to NCERT, the nucleolus is a spherical structure present in the nucleoplasm. Since it is not membrane-bound, its content is continuous with the rest of the nucleoplasm. The primary function of the nucleolus is to serve as a site for active ribosomal RNA (rRNA) synthesis. Transcription of messenger RNA (mRNA) occurs generally in the nucleoplasm, protein synthesis occurs on ribosomes in the cytoplasm or rough endoplasmic reticulum, and lipid synthesis occurs in the smooth endoplasmic reticulum. Answer: Acti
