👉 Nucleus is a part of an organism that contains the genetic material, which is essential for the development and functioning of the body. It is composed of atoms called nucleotides (adenine, thymine, guanine, cytosine), which are arranged in specific patterns to form the DNA or deoxyribonucleic acid (DNA). The nucleus is located within a cell's central region, where it contains the genetic information that determines an organism's traits and functions.
