Genetics: Gene Expression
MCAT Basics (from MedSchoolCoach)
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...
