BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.

Detailed explanation-2: -The organic molecules that are nucleic acids are DNA and RNA. DNA is the genetic material of the cell. It is the ultimate source of instructions for coding for proteins. RNA has several functions in the cell.

Detailed explanation-3: -Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.

Detailed explanation-4: -We now know that the DNA carries the hereditary information of the cell (Figure 4-2).

Detailed explanation-5: -The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.
