Which part of the cell assembles precursors of ribosomes within the nucleus? Answer. The nucleolus (also called nucleole) is a non-membrane bound structure composed of proteins and nucleic acids found within the nucleus and is the part of the cell assembles precursors of ribosomes within the nucleus.
The two ribosome sub-units disengage, separate and are re-used or broken down. Summary: Nearly all the proteins required by cells are synthesised by ribosomes. Ribosomes are found âfreeâ in the cell cytoplasm and also attached to rough endoplasmic reticulum. Ribosomes receive information from the cell nucleus and construction materials from the cytoplasm.
