Molecular Biology Fundamentals: DNA, RNA, and Gene Expression

Understanding how genetic information is stored, copied, and expressed is crucial for anyone entering biotechnology, medicine, or advanced science fields. This course demystifies the complex machinery of life. By the end of this course, you will have a solid grasp of the Central Dogma, the molecular mechanisms involved in DNA handling, and the basics of gene regulation, preparing you to tackle more complex topics with confidence. What you'll learn: * Understand the detailed chemical structure and function of DNA and various types of RNA. * Master the steps and enzymatic mechanisms required for accurate DNA replication and repair. * Apply knowledge of transcription and translation, the core processes of gene expression. * Analyze the fundamental principles governing prokaryotic and eukaryotic gene regulation. * Practice reading and interpreting genetic code and understanding mutation types. * Learn basic concepts of modern molecular analysis techniques, including PCR and sequencing methods. This course begins with foundational definitions and the chemical nature of nucleic acids before progressing through the core processes of the Central Dogma and control mechanisms. Written exercises are integrated throughout the material to reinforce key concepts and check your comprehension. This course is designed for absolute beginners, including students and professionals new to biology or preparing for foundational science exams. No prior knowledge of molecular biology is required.
