Lab Trash

tags: Lab Trash, recycle, molecular biology, cell biology, streaming video I’ve been telling you about the perils of plastics, but some of the worst plastics offenders are molecular and cell biologists. Nearly every experiment that we do uses incredible amounts of plastics. In cell biology or molecular biology labs the emphasis is on working sterile,…

tags: How Proteins Are Made From DNA in a Living Cell, biology, molecular biology, DNA, streaming video This video uses the latest research to create an animation of how DNA gives rise to proteins in a living cell. But do you think the word “machine” is correct? I have difficulty with the use of that…

tags: How DNA is Replicated in a Living Cell, biology, molecular biology, DNA, streaming video I still remember when I learned how DNA (Deoxyribonucleic Acid) replication occurs, and it was like a lightning bolt from the sky: it changed my view of the world and a molecular biologist was born. This video uses the latest…
