Including one of myloweslife a retrovirus that specifically attacks myloweslife the white blood cells (T-cells). ARN retrovirus is an animal virus that has ADN stage. The virus has an enzyme, reverse transcriptase, the enzyme that converts a single chain of ARN (as printed) into a double chain copy ADN (cADN). Furthermore, cADN joining ADN ADN host following the host's replication. At the time of ADN host of replication, directly ADN participate virus replicates.
The herpes virus is a DNA virus with a double chain which is then copied into MARN.
Influenza virus replication cycle is almost the same as the herpes virus replication cycle. However, the influenza virus genetic material in the form of a single chain of ARN which then undergoes replication into MARN.
ARN paramyxovirus is a kind of virus which then replicates into MARN. Paramyxovirus is a cause measles and mumps
2.7 ROLE OF VIRUS IN LIFE
Some viruses exist that can be used in genetic recombination. Through gene therapy, gene evil (causing infection) contained in the altered virus into good gene (healer) is called a vaccine. Examples manufacture polio vaccine, rabies, hepatitis B, influenza, measles, and MMR (Measles, Mumps, Rubella) for smallpox mumps, and measles.
In general, viruses are rnerugikan. The virus is very well known as a cause of infections in humans, animals, and plants. So far no living thing that is resistant to the virus. Each virus specifically attacks the specific cells of its host. The virus can infect plants, animals, and humans that cause disease.
