Question

Explain the structure of the nucleus in a living cell​

Answer 1

Look at the explanation

Step-by-step explanation:

Nucleus is situated in the cytoplasm of the cell.

Usually, it is round but many different shaped nuclei can be seen in some cells.

It is surrounded by two porous membranes called nuclear membranes which remain continuous with the Endoplasmic Reticulum.

Within the nuclear membrane is present a liquid substance called nucleoplasm.

Nucleoplasm contains two types of chromatin material: Heterochromatin and Euchromatin.

Chromatin fibres are thin thread-like structures composed of DNA and proteins.

These fibres condense to form short thick chromosomes during cell division and become visible.

DNA molecules transfer hereditary information from one generation to the next.

Answer 2

The nucleus contains nearly all of the cell's DNA, surrounded by a network of fibrous intermediate filaments and enveloped in a double membrane called the "nuclear envelope". The nuclear envelope separates the fluid inside the nucleus, called the nucleoplasm, from the rest of the cell.
