Lesson 3.1: Principles of Genetics and Molecular Biology

This lesson introduces the fundamental principles of heredity, including Mendelian genetics, chromosomal theory, and patterns of inheritance. Students also explore molecular biology topics such as DNA structure, replication, transcription, and translation in a logical sequence.

Complex genetic concepts are simplified through step-by-step explanations and conceptual flowcharts. This approach helps students confidently solve numerical, diagram-based, and reasoning questions in competitive exams.
