Question

Write a note on nuclear sap.

Answer 1

Similar to the cytoplasm of a cell, the nucleus contains nucleoplasm, karyoplasm, or nucleus sap. The nucleoplasm is one of the types of protoplasm, and it is enveloped by the nuclear membrane (also known as the nuclear envelope). The nucleoplasm includes the chromosomes and nucleolus. 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. The main function of the nucleoplasm is to serve as a suspension substance for the organelles inside the nucleus. It also helps maintain the shape and structure of the nucleus, and plays an important role in the transportation of materials that are vital to cell metabolism and function.
