MCAT Basics (from MedSchoolCoach)

Explore the fascinating world of the reproductive system! Discover the intricate processes of spermatogenesis and oogenesis, and how sperm and eggs journey through human reproduction. Unravel the hormonal dance during the menstrual cycle, learn how fertilization occurs, and uncover the connection between maternal age and Down Syndrome risk. Dive into early embryonic stages, from morula to blastocyst, and understand germ layer formation and its significance. Get ready for an engaging deep dive into biology and biochemistry!

In this episode, we explore key topics in genetics, including how sex-linked and autosomal traits are inherited. We'll break down inheritance patterns using real-world examples, like X-linked recessive diseases, and walk through Punnett square problems to show how these traits are passed down. We also cover the regulation of gene expression, focusing on epigenetic changes such as DNA methylation and how genetic imprinting impacts which genes are expressed. You'll gain insight into transcriptional and post-transcriptional control mechanisms in prokaryotes and eukaryotes, along with the processes of DNA repair that maintain genetic stability. Finally, we discuss important genetic lab techniques, such as PCR, blotting methods, and fluorescence in situ hybridization (FISH), and how they are used in gene analysis and diagnostics.
