Which conjegated molecules play important role in gene expression___________?

Explanation

Nucleohistones consist of DNA associated with histone proteins and help package DNA into chromosomes, influencing which genes are accessible for expression. Glycoproteins and glycolipids mainly function in membranes, recognition and secretion. Students may choose glycoproteins because they are important in cell signalling, but nucleohistones are the conjugated molecules directly linked with gene regulation.
