MCAT Basics Podcast

DNA Replication and Central Dogma

DNA replication and the central dogma are fundamental concepts in molecular biology, and breaking down the different replication methods and the processes of transcription and translation is crucial for understanding how genetic information is expressed and passed on in cells.

In the first part of our episode, we’ll break down DNA replication, exploring the concepts of conservative, semi-conservative, and dispersive replication, unraveling the mechanisms that drive this fundamental process.

Later, we’ll focus on transcription and translation, delving into the nuances between prokaryotic and eukaryotic organisms. We’ll uncover the mechanisms by which genetic information is transcribed from DNA to RNA and then translated into proteins, all while considering the diverse cellular locations where these processes take place.
