I'm the first black scientist to research how seasonal hydrological changes impacted flocculent organic matter dynamics in the Everglades. It was truly one of the best experiences of my life and I had so much fun doing this in grad school. Happy Black History Month 🖤. #biologist #researchscientist #biologymajor #scientist #stem

All A’s in every other class, by the way. 😂 But I’m having so much fun learning about life at its most foundational level. I’m also realizing that I’m experiencing a little test anxiety. My professor’s teaching style doesn’t align with how I learn best, but that’s no excuse. He won’t be the last professor whose teaching style doesn’t align with my learning style, so I’m learning how to adapt and keep moving forward. 🤝🏾 #premed #premedstudent #biologymajor #vlog

![🎥 Clockwork on yt go sub to their channel 🎵 @DeLevac "Eukaryotic DNA replication is a highly dynamic and tightly regulated process. Replication involves several dozens of replication proteins, including the initiators ORC and Cdc6, replicative CMG helicase, DNA polymerase α-primase, leading-strand DNA polymerase ε, and lagging-strand DNA polymerase δ. These proteins work together in a spatially and temporally controlled manner to synthesize new DNA from the parental DNA templates. During DNA replication, epigenetic information imprinted on DNA and histone proteins is also copied to the daughter DNA to maintain the chromatin status. DNA methyltransferase 1 is primarily responsible for copying the parental DNA methylation pattern into the nascent DNA. Epigenetic information encoded in histones is transferred via a more complex and less well understood process termed replication-couple nucleosome assembly. Here, we summarize the most recent structural and biochemical insights into DNA replication initiation, replication fork elongation, chromatin assembly and maintenance, and related regulation mechanisms. Although the double helix structure of DNA is elegantly simple, the molecular machinery that duplicates the DNA is remarkably complex. Seventy years since the discovery of the first DNA polymerase [1], we have gained an enormous amount of knowledge and mechanistic understanding of DNA replication. We have identified most (if not all) DNA polymerases, including five bacterial and sixteen archaeal/eukaryotic polymerases [2]." #molecularbiology #cellbiology #apbio #apbiology #dnareplication #dna #genetics #biologymajor #premed](https://ttanon.com/i/c/7417212592478752046-720.webp)
