Question

Nucleoplasm is also called
A. Nuclear sap
B. Karyolymph
C. Both A and B
D. Nuclear matrix

Answer 1

Hint: Nucleoplasm is a protoplasm type which is enveloped by a nuclear envelope. It involves chromosomes and nucleolus. Substances like nucleotides which are necessary for DNA replication and enzymes which help in activities that occur in nucleus are dissolved in the nucleoplasm.

Complete step by step answer:
Functions of nucleoplasm are:-
Nucleoplasm acts as a suspension medium for nucleus components involving nucleolus and chromatin.
Nucleotides necessary for DNA replication and enzymes which direct the nuclear processes are found in the nucleoplasm.
Nuclear lamina present in nucleoplasm helps to localize and organize genetic information during cell division.
Nucleoplasm is an entity of plant cell nucleus and can be defined as a fluid-filled matrix which is present within the nuclear membrane. Nucleoplasm is protected and separated by a double membrane envelope from cytoplasm.
Nucleoplasm and cytoplasm are regulated by nuclear pores and these pores are connected to a complex of nucleoplasmic channels.
The other components in nucleoplasm are DNA chromosomes.
Small sections of DNA that are uncondensed during cell interface are known as heterochromatin. The space between these chromatin elements is inter chromatin space.
Nucleoplasm also known as karyolymph and nuclear sap.

So , the correct answer is Both A and B.

Note: Nucleoplasm was coined in 1875 by Van Beneden . Nucleoplasm is made up mostly of water, dissolved ions and a mixture of various molecules.
