Unit 4 Cell Communication and Cell Cycle

Cells aren’t just tiny blobs—they talk to each other! This unit focuses on how cells send and receive signals, how they respond, and how they decide when (or if) to divide. We’ll dissect signal transduction pathways, look at cell cycle checkpoints, and make predictions about what happens when regulation fails (hello, cancer). It’s molecular coordination at its finest—and most dangerous.
