Mitochondria are descended from bacteria that invaded cells 1.5 billion years ago and never left. The mitochondrial genome is like that of bacteria: circular double-stranded DNA, only smaller. And just like the genome of bacteria, RNA can be made from both strands of mitochondrial DNA – which results in the formation of dsRNA. Fortunately there …
From the 13th International Symposium on dsRNA viruses in Belgium, Vincent speaks with Harry Greenberg about his career and his work on rotaviruses, noroviruses, hepatitis B virus, and influenza virus. <span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span><span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span><span data-mce-type=”bookmark” style=”display: inline-block; width: …
Some antiviral drugs, like acyclovir for treatment of herpes simplex virus infections, are chain terminators that block RNA or DNA synthesis. They are modified nucleotides that can be incorporated into a growing RNA strand, but no additional nucleotides can be added. Amazingly, a cell protein has been found that can synthesize antiviral chain terminators.
Anne Simon joins the TWiV team to talk about plant viruses, including plum pox virus that devastates nut and stone fruit trees, and a geminivirus protein that regulates viral DNA synthesis. <span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span><span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span>&lt;span data-mce-type=”bookmark” style=”display: inline-block; …
The Graduate School of Biomedical Sciences at the Icahn School of Medicine at Mt. Sinai recently conducted the first PhD Lab Coat Ceremony in New York City. I was honored to be the Keynote Speaker at this event. My address follows. Forty-three years ago this month I was in your shoes. I had just joined …
