Vacillating Meaning In Urdu with Detail
SV40 is an abbreviation for simian vacuolating virus 40 or simian virus 40, a polyomavirus that is found in both monkeys and humans. Like other polyomaviruses, SV40 is a DNA virus that has the potential to cause tumors in animals, but most often persists as a latent infection. SV40 has been widely studied as a model eukaryotic virus, leading to many early discoveries in eukaryotic DNA replication and transcription. The discovery of SV40 revealed that between 1955 and 1963 around 90% of children and 60% of adults in the U.S. were inoculated with SV40-contaminated polio vaccines.
