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 the little 'dots' that live on the rough endoplasmic reticulum surrounding the nucleus of a cell. They are very important organelles that make polypeptide assembly possible. In this lesson, we're going to focus on the ribosome and the role it plays in helping to begin genetic translation.
