Detailed explanation-1: -We now know that the DNA carries the hereditary information of the cell (Figure 4-2). In contrast, the protein components of chromosomes function largely to package and control the enormously long DNA molecules so that they fit inside cells and can easily be accessed by them.

Detailed explanation-2: -DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA.

Detailed explanation-3: -They have their own genetic material, separate from the DNA in the nucleus, and can make copies of themselves. Nucleus. The nucleus serves as the cell’s command center, sending directions to the cell to grow, mature, divide, or die. It also houses DNA (deoxyribonucleic acid), the cell’s hereditary material.

Detailed explanation-4: -Genetic material, including genes and DNA, controls the development, maintenance and reproduction of organisms. Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes).

Detailed explanation-5: -The main function of the genetic material of the cell is to contain the instructions for cell structure and function. DNA acts as the blueprint for all cellular components and the ultimate composition of organisms. To do this, DNA holds the information for building proteins.
