Scientists Removed an Extra Chromosome Using CRISPR 😳🧬

In this AP Biology lesson, we cover 6.6 Gene Expression and Cell Specialization, one of the most important topics for understanding how genetically identical cells develop into specialized cell types with unique structures and functions. You'll learn how gene expression regulates cell differentiation, why different cells activate different genes, and how these processes contribute to growth, development, and organismal function. Whether you're preparing for the AP Biology exam, reviewing Unit 6,
