That enzyme is called reverse transcriptase. Blocking action of this enzyme will lead to inhibition of viral genome replication. The AZT inhibits an enzyme that would ... WebMar 6, 2024 · An antiviral agent must act at one of five basic steps in the viral replication cycle in order to inhibit the virus: (1) attachment and penetration of the virus into the host cell, (2) uncoating of virus (e.g., removal of the protein surface and release of the viral DNA or RNA), (3) synthesis of new viral components by the host cell as directed ...

WebThe response of Legionella pneumophila to antibiotics that inhibit cell-wall, protein and DNA synthesis was examined by electronmicroscopy, MIC estimations and viable counts. Ampicillin, cefotaxime, methicillin, erythromycin, rifampicin and ciprofloxacin, each used separately at 20 times their respective MIC values, showed activity against L ... WebAZT is a type of anti-HIV drug called a nucleoside analogue (“nuke”). The most common side effects of AZT can include headache, nausea, and loss of appetite. More rarely, it can cause anemia and low white blood cell counts. It is usually taken at a dose of 300 mg twice daily, with or without food.
WebDNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.
WebNucleoside analogues are nucleosides which contain a nucleic acid analogue and a sugar.
