Overview
Similar to the cytoplasm of a cell, the nucleus contains nucleoplasm or nuclear sap. The nucleoplasm is one of the types of protoplasm, and it is enveloped by the nuclear membrane or nuclear envelope. The nucleoplasm is a highly viscous liquid that surrounds the chromosomes and nucleoli. Many substances such as nucleotides (necessary for purposes such as the replication of DNA) and enzymes (which direct activities that take place in the nucleus) are dissolved in the nucleoplasm. A network of fibers known as the nuclear matrix can also be found in the nucleoplasm. The nucleoplasm is partly made up of nucleohyaloplasm and nucleosol. The nucleoplasm is also colorless.
Introduction
A plasm is a formative or formed material; i.e., something molded. Usually a formed material keeps it shape once the mold is removed. Should something be glassy or transparent it can be said to be hyaloid. Whether a fluid is molded or liquid is often a matter of viscosity and whether a fluid is transparent, translucent, or opaque is often a matter of absorption.
Binding to the nucleoplasm
As a molded material, the nucleoplasm can serve as a target for binding molecules. For example, thyroid hormones have been found to bind to it.[1]
