Detailed explanation-1: -Nucleus. Known as the cell’s “command center, ” the nucleus is a large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information.

Detailed explanation-2: -Nucleus-The nucleus is the control center of the cell. It is the largest organelle in the cell and it contains the DNA of the cell. DNA (Deoxyribonucleic Acid) contains all the information for cells to live, perform their functions and reproduce.

Detailed explanation-3: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Detailed explanation-4: -Nucleus: The nucleus is the most important organelle of the cell which controls all the cellular activity. It contains the genetic material in the form of DNA which is protected by the nuclear envelope.

Detailed explanation-5: -The nucleus is often referred to as the ‘brain’ of a cell because this is where the DNA is located. The instructions for the production of functional products are contained within the nucleus, and so it is responsible for a large part of a cell’s activities.
