Question

What is the derinition of nucleus?

Answer 1

In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, "little nut" or kernel) is a membrane-enclosed organelle found in most eukaryotic cells. It contains most of the cell's genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are the cell's nuclear genome. The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression.

Answer 4

NUCLEUS IS THE MOST SIGNIFICANT PART OF THE CELL AND IS HIGHLY DIFFERENTIATED AND SPECIALISED GLOBULAR, ELLIPSOIDAL, SPHERICAL OR DISC-SHAPED PROTOPLASMIC BODY EMBEDDED IN CYTOPLASM. THE VISCOSITY OF NUCLEUS IS HIGHER THAN THAT OF CYTOPLASM. NUCLEUS IS ALWAYS FORMED FROM PRE-EXISTING ON E. THE INDIVIDUAL COMPONENTS OF THE NUCLEUS ARE AS FOLLOWS;

1.NUCLEAR MEMBRANE

2.NUCLEOPLASM

3.NUCLEAR RETICULUM

4.NUCLEOLUS

5.CHROMOSOME
