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 […]

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 […]

MCQ on RNA Structure and Functions
RNA, or Ribonucleic Acid, is a molecule essential for various biological processes. It consists of a single strand of nucleotides, including adenine (A), uracil (U), cytosine (C), and guanine (G). RNA plays a central role in protein synthesis, gene expression, and carries genetic information in some viruses. This is an […]

MCQ on Nucleosome Model of Chromosome
A nucleosome is the basic unit of DNA packaging in eukaryotes. It consists of a segment of DNA wrapped around a core of histone proteins. Nucleosomes help condense and organize DNA, regulating access for processes like transcription and DNA replication. This is an MCQ on Nucleosome Model and Organization of […]

MCQ on Purine Synthesis (Nucleic Acid Biosynthesis)
Purine synthesis is a biochemical pathway that cells use to produce purine nucleotides, the building blocks of DNA and RNA. It involves a series of enzymatic reactions that convert precursor molecules into purines, such as adenine and guanine. This pathway is essential for the synthesis of genetic material and various […]
