Step-by-step solution

Nucleolus is a non-membrane bound structure in the nucleoplasm which is the site for active ribosomal RNA (rRNA) synthesis. Kinetochores are disc-shaped structures present on the sides of the centromere, which serve as the sites of attachment of spindle fibres to the chromosomes during cell division. Chromatin is a highly extended and elaborate nucleoprotein fibre network containing DNA and basic proteins called histones, along with some non-histone proteins and RNA. Nuclear pores are formed by the fusion of the tw
