MCAT Basics (from MedSchoolCoach)

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.

Learning and memory are foundational concepts that play a critical role in acing the MCAT, especially in the Psych/Soc section.

In this episode, host Sam Smith discusses the key concepts of learning and memory, covering the brain structures involved in memory formation, like the hippocampus and amygdala, as well as the different types of memory—explicit, implicit, and working memory. Sam also explores types of learning, including latent learning, observational learning, and the essential principles of classical and operant conditioning, and more.

A foundational part of the MCAT, light and optics bridge the gap between physics and biology, making them vital for your exam preparation.

In this episode, Sam Smith breaks down the fundamentals of light, covering both its wave and particle properties. From the energy of photons and the photoelectric effect, to wave behavior and the principles of refraction and reflection, Sam simplifies complex concepts to help you grasp key equations and principles. You'll also learn about lenses, ray tracing, and the real-life applications of polarization.
