DNA, the blueprint of life, resides within the nucleus of our cells. Yet, the presence of DNA in red blood cells, the oxygen-carrying workhorses of our circulatory system, has long been a subject of debate. In this article, we will delve into the intricacies of red blood cell biology to unravel the answer to the … Read more

Conjugation, a pivotal process in horizontal gene transfer, enables direct exchange of genetic material between two closely related bacteria. This exchange involves the transfer of plasmids, transposons, and other mobile genetic elements, facilitating the dissemination of advantageous traits among bacterial populations. The conjugation process requires a physical connection via a sex pilus, providing a conduit … Read more

Mitotic inhibitors are a diverse group of agents that target the cell cycle, mitosis and microtubules. They include classic cytotoxic agents, such as vinblastine and vincristine, that bind to tubulin and inhibit the formation of microtubules. Vinblastine arrests mitosis in metaphase and vincristine arrests mitosis in prometaphase. Checkpoint kinase inhibitors, such as AZD7762, inhibit the … Read more
