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.
1 In eukaryotes the ribosome, an 80S ribosome, is made of a 40S small subunit + a 60S large subunit. 2  In prokaryotes the ribosome is 70S and made of a 50S large subunit + a 30S small subunit. 3  Eukaryotic chloroplasts and mitochondria contain prokaryote-like 70S ribosomes.
