In the human body, health is maintained through the interconnectedness of organ systems, proper posture, and stable biochemical metabolism.
There are many different roles that nucleic acids, which include DNA and RNA, play in the human body and in other living organisms. Scientists continue to identify new and different functions of nucleic acids on a regular basis.

Cells are the simplest units of life. In some organisms, cells function as the complete living creature--bacteria, for instance, consist of only a single cell. In other organisms, many cells working together comprise the organism.

Nucleic acids are large biomolecules, and include both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA carries your cells' genetic information. RNA uses this genetic information, and helps the cells make proteins.

Your digestive and respiratory systems, at first glance, seem very separate in their activities. In reality, however, the systems work together intimately in several ways. The results of respiratory activity allow the digestive tract to function, and vice versa.

The male reproductive system depends upon the action of many different hormones or chemicals, produced by various body glands and enter systemic circulation. Some of these hormones, called βtropicβ hormones, cause other hormones to release.

Proteins are important structural and functional biomolecules that are a major part of every cell in your body. There are 2 nucleic acids -- DNA and RNA. Your cells make proteins by following the instructions encoded in your DNA, which is genetic material and a type of nucleic acid.

Humans--and all other living organisms--need nucleic acids. The nucleic acids, which include deoxyribonucleic acid, or DNA, and ribonucleic acid, or RNA, encode genetic information and allow humans and other organisms to follow their genetic instructions.
