Chinese New Year is the most important and longest of all Chinese festivals, celebrated in Chinese communities worldwide. Chinese New Year activities include: 1  Making offerings to household deities. 2  Wearing new clothes, particularly in red. 3  Hosting a large banquet for family and friends.
A provirus is a virus genome that is integrated into the DNA of a host cell.In the case of bacterial viruses (bacteriophages), proviruses are often referred to as prophages.his can result in the destruction of its host cell because the cell's protein synthesis machinery is hijacked to produce more viruses. Proviruses may account for approximately 8% of the human genome in the form of inherited endogenous retroviruses.
An enzyme (protein) that's part of the human immunodeficiency virus reads the sequence of viral RNA nucleic acids (yellow in graphic) that have entered the host cell and transcribes the sequence into a complementary DNA sequence (shown in blue). That enzyme is called reverse transcriptase .Without reverse transcriptase, the viral genome couldn't become incorporated into the host cell, and couldn't reproduce. Reverse transcriptase sometimes makes mistakes reading the RNA sequence.The result is that not all viruses produced in a single infected cell are alike.Instead, they end up with a variety of subtle molecular differences in their surface coat and enzymes.everse transcriptase sometimes makes mistakes reading the RNA sequence.
