Document Summary

Every day we are alive, humans encounter potentially harmful disease causing organisms, or pathogens , like bacteria or viruses. Yet most of us are still able to function properly and live life without constantly being sick. That"s because the human body requires a multilayered immune system to keep it running smoothly. The two main classes of the immune system are the innate immune system and the adaptive immune system, or acquired immunity . In this article, we"ll discuss the first line of defense: the innate immune system. In order to be effective, the immune system needs to be able to identify which particles are foreign, and which are a part of your body. Let"s define some terms before we jump in to how this works: self refers to particles, such as proteins and other molecules, that are a part of, or made by, your body. They can be found circulating in your blood or attached to different tissues.

HIV has which of the following characteristics?

A

It has an enzyme called reverse transcriptase which causes the DNA to reverse the nucleotide sequence in messenger RNA.

B

It is a retrovirus meaning that it reverses the order of protein production in that the virus affects the DNA in the cell to make the protein.

C

It is an anti-retrovirus meaning that it attacks the DNA causing the development of new HIV particles.

D

It has a short incubation period which means that the symptoms show up also immediately after infection.
