A typical animal cell contains more than 40,000 different kinds of molecules. In the past 20 years, great progress has been made in understanding how these molecules combine and interact to form a living creature. Prof. Emeritus Barry Bowman organizes the course and offers two lectures. Two other professors from the Molecular, Cell and Developmental Biology Department at UCSC present lectures covering topics related to their research programs. These talks are intended for a general audience. A scientific background or knowledge of biology is not expected. Barry Bowman, the course coordinator, will begin with a basic review of genes, proteins and cells. Lecture #1. Prof. Emeritus Barry Bowman: An introduction to the basics of molecular biology Lecture #2. Assistant Prof Josh Arribere: How quality control protects our cells Lecture #3. Prof. Martha Zuniga: SARS Wars: Immune defenses against SARS-CoV-2 and COVID-19 pathology Lecture #4. Prof. Emeritus Barry Bowman: Digging deeper into DNA Barry Bowman is Professor Emeritus of Molecular, Cell and Developmental Biology at UCSC.

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! In this foundational cell biology lecture, Professor Zach Murphy provides a detailed and organized overview of Cell Structure and Function, helping you understand the roles of key organelles and how they work together to maintain cellular homeostasis. We begin by breaking down the plasma membrane, emphasizing its phospholipid bilayer, membrane proteins, and selective permeability. From there, we explore major intracellular structures, including the nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, and mitochondria—explaining their individual functions and how they coordinate to support growth, metabolism, protein synthesis, and waste management. The lecture also covers the cytoskeleton, detailing the roles of microfilaments, intermediate filaments, and microtubules in maintaining cell shape, intracellular transport, and cell division. We link structure to function throughout, making understanding how cellular dysfunction can lead to disease easier. This lecture is the perfect starting point for mastering cell biology and sets the stage for understanding more complex processes like signaling, transport, and division.
