- Cover your mouth when you cough or sneeze.
Are humans made of DNA?
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. Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people.
How do viruses enter your body?
In humans, viruses that cause disease like cold and flu are spread through bodily fluids, like spit or snot. The virus is so small that it leaves our bodies in these fluids, and can even float through the air in droplets from a sneeze or cough. The virus can enter the body through the eyes, nose, or mouth.

What is DNA?
- Your genome? is made of a chemical called deoxyribonucleic acid, or DNA for short.
- DNA contains four basic building blocks or ‘bases?’: adenine? (A), cytosine? (C), guanine? (G) and thymine? (T).
- The order, or sequence, of these bases form the instructions in the genome.
- DNA is a two-stranded molecule.
