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 […]
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 […]
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 […]
The ABC model of flower development is a genetic framework that explains how specific genes control the formation of floral organs in plants. It consists of three classes of genes: A (for sepals and petals), B (for petals and stamens), and C (for stamens and carpels). Combinations of these genes’ […]
Transposons, also known as “jumping genes,” are DNA sequences in the genome that can move or “transpose” to different locations within the genome. They can disrupt genes, cause mutations, or regulate gene expression. Transposons play a role in evolution and genetic diversity but can also lead to genetic disorders if […]
