The Doppler Effect is a crucial concept for the MCAT, particularly in the Chemistry & Physics section. We'll explore how the Doppler effect occurs when a wave source moves relative to an observer, affecting the observed frequency and wavelength. Using practical examples like an a ...  Show more

In this episode, we cover the topic of viruses. We explore a comprehensive range of subtopics including the definition and structure of viruses, their life cycles, and the differences between transduction and transfection. We also discuss virus classification, viral mutations, an ...  Show more

Modeling evolutionary processes goes way beyond the Hardy-Weinberg Equilibrium we all learned in biology class. Natural selection comes from many sources like resources availability, mate preferences, competition. Modeling entire populations of organisms of different species is t ...  Show more

From whole populations to individual cancers, we're taking a look at genes and evolution. We're also talking about dogs and their diseases, shining a light on Van Gogh's sunflowers, and wondering whether the USB-sized DNA sequence is hope or hype. Plus we've got our gene of the m ...  Show more

Here we survey of the causes and consequences of genetic mutation, including a discussion of mechanisms of endogenous and induced mutations, rates of mutation, types of single nucleotide mutations, and the phenotypic effects of mutation. We also discuss various mechanisms for det ...  Show more

In this episode we connect genetics + central dogma to the next big step: how cells copy DNA and what happens when it goes wrong.What you’ll learn (MCAT-high yield):Semi-conservative replication: why each daughter DNA has one old + one new strandOrigins of replication & replicati ...  Show more
