Chromosomes and DNA is a fundamental topic in FSC Biology and crucial for MDCAT and entry test preparation. DNA (Deoxyribonucleic Acid) is the genetic material that stores the instructions for the growth, development, and functioning of all living organisms. It is organized into chromosomes, which are thread-like structures found in the nucleus of eukaryotic cells. Each chromosome carries genes, the basic units of heredity, which determine inherited traits. Understanding DNA structure, replication, and chromosome behavior during cell division (mitosis and meiosis) is essential for explaining genetics, inheritance, and evolution. This topic is highly important for FSC board exams and MDCAT entry test preparation, and PLS Academy provides detailed explanations, diagrams, and exam-focused MCQs to help students master these concepts effectively.
