Vedclass · Answer

(A) The nucleolus is a spherical structure present in the nucleoplasm of the nucleus.It is not a membrane-bound structure,meaning it lacks a limiting membrane.Its primary function is the active synthesis of ribosomal $RNA$ $(rRNA)$.Cells that are actively involved in protein synthesis contain larger and more numerous nucleoli.Spindle formation is a function of the centrosome/microtubules,not the nucleolus.Therefore,the statement that it is a site for active ribosomal $RNA$ synthesis is correct.
