Molecular Cloning Methods (CMB part 2)

Memory isn’t stored in a single place or a single cell—it’s embedded in subtle, widely distributed changes at synapses. In this episode, we explore how neuroscientists moved from abstract theories of memory to concrete biological mechanisms. We follow the trail from Hebb’s insigh ...  Show more

The human brain contains roughly 85 billion neurons, and somehow each one makes the right connections at the right place, in the right order. In this episode, we explore how such astonishing precision emerges during brain development, using the visual system as our guide—from ret ...  Show more

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 ...  Show more

00:47 An edited genetic code that prevents viral infectionResearchers have engineered bacteria with synthetic genomes to be immune to viral infection. The team streamlined the bacteria’s genetic code, and re-engineered the protein-producing machinery to insert the wrong amino aci ...  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
