WebDec 21, 2024 · Blocking the synthesis of full-length DNA inhibits viral replication. However, toxicity is a concern with this mechanism, since it may also inhibit DNA synthesis in healthy cells. Fortunately, it is selective with roughly 100-fold more activity against HIV reverse transcriptase than human DNA polymerases [ 2 ]. WebAZT is incorporated into DNA when the nucleotide incorporated into the growing chain of DNA attacks the AZT-triphosphate instead of a normal nucleotide. When AZT is thus incorporated into DNA, DNA synthesis stops because AZT does not have a another nucleotide triphosphate.

WebMar 2, 2015 · At high doses, >1mM, AZT can act as a substrate for human DNA polymerases. Thankfully, AZT is about 100 fold more selective for HIV reverse transcriptase than human DNA polymerase. The mitochondrial DNA polymerase seems to be a little more sensitive to AZT than other human DNA polymerases. WebHuman immunodeficiency virus (HIV) is the retrovirus that causes AIDS. AZT was one of the first drugs designed to interfere with retroviral DNA synthesis. When cells take up AZT, they convert it to AZT-triphosphate. Explain how AZT interferes with DNA synthesis. WebDNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and synthesize DNA in the … Alternatively, this can also mean a region of DNA that is replicated together.

"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. " - Explain how azt interferes with dna synthesis
