The protoplasm present in the nucleus of eukaryotic cells. It is a highly viscous liquid enveloped by the nuclear membrane, regulating passage of molecules between the nucleoplasm and the cytoplasm[1]. It consists mainly of water, dissolved ions, and a complex mixture of other molecules. 32% of all human proteins have experimentally shown to be present within the nucleoplasm[2]
Function
The nucleoplasm acts as a suspension medium for components of the nucleus including the nucleolus, and chromatin. Nucleotides required for DNA replication and enzymes involved in other nuclear processes are also found dissolved within the nucleoplasm[3]. The nucleoplasm plays a role in the maintenance of the shape and structure of the nucleus[4]. The nuclear matrix is present within the nuclear hyoplasm, the liquid component of the nucleoplasm[5]
