MCAT Basics (from MedSchoolCoach‪)‬ MedSchoolCoach

This podcast focuses on the eye. It begins with a brief overview of the eye's anatomy and physiology. The discussion then shifts to rods, cones, and the phototransduction pathway. The final section addresses perception.
Key topics include visual field processing, differences between binocular and monocular cues, and feature detection (covering both Magno and Parvo pathways).

To continue our discussion on the immune system, in this episode, we will cover the second type of immune system – the adaptive immune system. 
 
We start with covering some vocabulary that you’ll need to know to understand the immune system, then we move into the cells that make up the adaptive immune system. Then we break down the two branches of the adaptive immune system -  humoral immunity including the discussion of B cells and cell-mediated immunity highlighting T cells.  
Don’t miss our previous episode on the other type of immune system, the innate immune system.

The immune system is split up into two main categories - the adaptive immune system and the innate immune system. 
This episode will cover the intricacies of the innate immune system beginning with an overview of its constituent cells. We will then explore three pivotal elements of the system: anatomical barriers, the general inflammatory response, and the complement system. This will show up in the bio/biochem section of the MCAT.
For additional reading on this topic, you can refer to the NIH’s Innate Immune System paper.

This episode of MCAT Basics covers several separation and purification techniques you may see on the MCAT. We’ll cover these techniques in three distinct categories: small molecules, proteins, and cells. 
Within the small molecule category, we’ll discuss extraction, crystallization and recrystallization, and chromatography (TLC and HPLC).
For proteins, we cover SDS-page, precipitation, soelectric focusing, and chromatography variations. Lastly, we’ll explain, within the world of cells, centrifugation, flow cytometry, and microfluidics.

This episode of MCAT Basics covers the world of circuits. We will explore electrical circuits and their fundamental principles.
We’ll start with dissecting the essential parameters that form the backbone of circuits: voltage, current, resistance, and power. These are the building blocks upon which all circuit dynamics are based.
Next, we'll explore a variety of circuit elements, from resistors to batteries, capacitors, and switches. Each of these components plays a vital role in shaping the behavior of circuits and understanding their functionality.
Finally, we'll delve into Ohm’s Law and Kirchhoff’s Law, two fundamental principles that govern circuit behavior. By grasping these laws, you'll gain essential insights into how circuits operate and how to analyze their dynamics effectively.

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.
