Detailed explanation-1: -The chromosomes carrying hereditary characters called genes are located in the nucleus of a living cell.

Detailed explanation-2: -chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness.

Detailed explanation-3: -The nucleus is a membrane-bound structure that contains the cell’s hereditary information and controls the cell’s growth and reproduction. It is the most prominent organelle in the cell. It is surrounded by a structure called the nuclear envelope.

Detailed explanation-4: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Detailed explanation-5: -The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
