Genetics: Gene Expression

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

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
