Problem description:

If we rule out the way of getting infected with AIDS

Is it possible to mutate into a virus by yourself?

Analysis:

HIV: Emergence time 1980 10 month.

● Location: Five young gay men were admitted to UCLA Hospital. These cases were later proved to be an unprecedented disease-"Acquired Immunodeficiency Syndrome" (AIDS).

● Spreading animals: It is not clear yet. Researchers may have found the natural host of the virus, or at least one of the hosts-green monkeys or African monkeys living in Africa. Traditionally, it is believed that AIDS patients are caused by eating the meat of animals such as monkeys or orangutans containing HIV. However, the defect of this theory is that AIDS is infected through blood and body fluids, and the dietary route is not accurate. Later, it was speculated that due to the hot climate and humid living environment in Africa, the living habits of all ethnic groups in Africa were difficult to integrate with the "civilized society", and various zoonotic infectious diseases developed rapidly and stubbornly in this area. On the other hand, in many places, especially rural tribes, it is very casual to have sex. Residents in some areas also have a custom passed down from generation to generation: using the blood of monkeys to * * * use the blood of people. They injected male monkey blood and female monkey blood into the thigh, pubic region and back arm of men and women respectively, and even treated female infertility and male impotence in this way. However, if we trace back to this custom in this area, the earliest age may be much longer than the history of AIDS epidemic, which makes this view doubtful. 1999 according to the latest research by three German biochemists, a large number of wild monkeys or orangutans are infected with HIV, but they will not get sick. When they are hunted and sold, blood-sucking stable flies will transfer HIV into the human body and cause diseases. Another possibility is that this blood-sucking fly bites the AIDS monkey and then bites people to spread the disease.

The mortality rate was 6 1%. There are at least 36 million cases so far.

1.HIV nucleic acid has four bases: A (adenine), G (guanine), C (cytosine) and U (uracil).

The Chinese name of AIDS is acquired immunodeficiency syndrome.

Aids virus is HIV, and HIV is human immunodeficiency virus in Chinese.

3. HIV is a retrovirus, and the so-called retrovirus must be an RNA virus, which is a single-stranded RNA.

The genetic material of Escherichia coli is DNA, which is double-stranded

Moreover, the basic components of RNA are adenine RNA (A), guanine RNA (G), cytosine RNA (C) and uracil RNA (U).

The basic components of DNA are adenine deoxynucleic acid (A), guanine deoxynucleic acid (G), cytosine deoxynucleic acid (C) and thymine deoxynucleic acid (T).
