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 […]

MCQ on DNA Structure and Functions
DNA (Deoxyribonucleic Acid) is a molecule that carries genetic information in living organisms. It consists of a double helix structure made up of nucleotides containing four bases: adenine (A), thymine (T), cytosine (C), and guanine (G). DNA serves as a blueprint for the development, functioning, and reproduction of cells and organisms. This is an MCQ […]
