In this molecular biology lecture, Professor Zach Murphy delivers a clear and structured overview of DNA Structure and Organization, laying the groundwork for understanding how genetic material is packaged, protected, and expressed in eukaryotic cells. We begin with the fundamental structure of DNA, highlighting the double helix, complementary base pairing, and antiparallel strands formed by nucleotide sequences. The lecture then transitions into how this DNA is organized within the nucleus, starting with histones and the formation of nucleosomes, followed by higher-order chromatin folding into euchromatin and heterochromatin. You’ll also learn how chromatin remodeling, histone modifications, and DNA methylation play essential roles in regulating gene accessibility and expression. We touch on the structural differences between prokaryotic and eukaryotic genomes and the functional implications of tightly vs loosely packed DNA. Whether you’re reviewing for a molecular biology course or trying to understand gene regulation and expression at a deeper level, this lecture provides the perfect foundation in DNA architecture.
