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.
Ribosomes are cellular organelles that assemble enzymes and other proteins according to the directions found in the DNA code. Structurally, ribosomes consist of two major subunits. The smaller subunit reads mRNA, and the larger subunit assembles amino acids into a peptide chain that will be folded into a protein.
