Chromosome Structure, Chemical Composition & Organization | Complete MDCAT Biology Lecture

In this complete MDCAT Biology lecture, we cover Chromosome Structure, Shape, Chemical Composition, Organization, and Functions in a clear, conceptual, and exam-oriented manner. This lecture explains how chromosomes are organized at the molecular level, including DNA, histone and non-histone proteins, nucleosomes, chromatin organization, and different chromosome shapes. Special focus is given to MDCAT-relevant concepts, common confusions, and high-yield points frequently tested in exams. 🔬 Topics Covered: Definition and structure of chromosomes Chemical composition of chromosomes (DNA, histones, non-histone proteins) Levels of chromatin organization Euchromatin vs heterochromatin Chromosome shape and types Functions of chromosomes MDCAT exam-focused tips and explanations This lecture is ideal for MDCAT, FSC, and pre-medical students who want strong conceptual understanding along with exam confidence.
