Giant Chromosomes Explained: The Key to Genetic Mapping

Giant Chromosomes: The DNA Maps We Can Actually See 🧬🔬 Not all chromosomes are microscopic! In this video, we look at the two famous types of giant chromosomes: Polytene and Lampbrush Chromosomes. These massive DNA structures are visible under a light microscope and were crucial for foundational discoveries in genetics. We'll compare and contrast them, covering: Polytene Chromosomes: How they form through endoreduplication in Drosophila salivary glands, their unique banding patterns, and what chromosome puffs tell us about gene activity. Lampbrush Chromosomes: How they form during meiotic prophase in amphibian oocytes, their role in rapid protein synthesis, and why their looped structure is key to understanding gene expression. #GiantChromosomes #Genetics #Biology #Polytene #Lampbrush #CellBiology #ScienceEducation #DNA #APBio
