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.

This podcast covers thermodynamics. First, I discuss the four laws of thermodynamics, as well as their application on the MCAT. Then, I break down enthalpy, Gibbs free energy, and entropy (briefly). Lastly, I cover the three types of heat transfer: conduction, convection, and radiation.

CORRECTION:

First Law of Thermodynamics is U =Q - W, I said 'U = Q + W'. For U = Q - W, W (work) is defined as work done BY the system on its surroundings.

This podcast covers cell and tissue types. First, I discuss the difference between eukaryotic and prokaryotic cells. I further break down these categories and talk about the differences between animal, plant, fungi, protozoa, archaea, and bacterial cells. Next, I talk about each of the four main tissue types: epithelial, muscle, connective, and nervous. The bulk of this section covers epithelial tissue.

This podcast covers renal physiology. I start with a brief introduction to renal anatomy, then discuss in detail renal physiology. Next, I introduce three hormones (ADH, aldosterone, and ANP) that effect the kidneys and discuss their effects on the nephron. Lastly, I talk about measurements of renal function.

This podcast covers identity and psychosocial development. First, I will define a few terms you may see on the MCAT regarding identity. Next, I will breakdown the following theories of identity development: Erickson’s psychosocial development theory, Freud’s theory of psychosexual development, Paiget’s development theory, Kohlberg’s moral development theory, George Herbert Mead’s the I and the me, Cooley’s looking glass self, and Vygotsky’s social development theory.

This podcast covers the main functional groups you will see on the MCAT. First, I will cover different physical properties (boiling point and solubility) of compounds containing the 8 most common functional groups: alcohols, ethers, aldehydes, ketones, carboxylic acids, esters, and amides. I then mention the difference in reactivities of different carboxylic acid derivatives. Last, I’ll introduce a few less common functional groups that you may see on the MCAT.

This podcast covers topics within electromagnetism. First, I will talk about charge and electric fields. This will include discussions on static charge, the amber effect, and electric potential. Then, I will introduce magnetism. I will discuss the concept of magnetism, force applied by a magnetic field, the right hand rule, and the magnetic characterization of different materials.

*Corrections*:

1. Electrostatic force is INVERSELY proportional to the distance between charges squared
2. Amperes = Coulombs/Second
3. I say that magnetic field lines travel in the same direction that Santa goes when he is done delivering presents. This assumes he lives on the South Pole. (i.e. he goes north to south when he is done delivering presents)
