MCQ on Central Dogma of Molecular Biology




The central dogma of molecular biology is a fundamental concept that describes the flow of genetic information in cells. It states that DNA encodes genetic instructions, which are transcribed into RNA, and then translated into proteins. This unidirectional process governs how genetic information is used to build and regulate living organisms. This is an MCQ on Central Dogma of Molecular Biology
