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

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

In this episode, Emma looks at mitosis, meiosis and the genome for your GCSE Biology exam. She looks at the process of producing gametes from meiosis, as well as the role of mitosis in sexual reproduction. Perfect for AQA, Edexcel, OCR, WJEC and CIE exam boards. Ideal for prep ...

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

Join Emma as she goes through everything you need to know about genetic inheritance for your GCSE Bio exam. She looks at the different effects of mutations, the role that alleles play in gene expression as well as phenotypes. Perfect for AQA, Edexcel, OCR, WJEC and CIE exam bo ...
