Bioenergetics is the study of how energy flows through living systems. At the cellular level, this energy currency is a molecule called Adenosine Triphosphate (ATP). The two most fundamental metabolic pathways that govern the flow of energy in the biosphere are photosynthesis (which captures energy) and cellular respiration (which releases it). They are intricately linked, forming...")

These materials are biological macromolecules—large, complex molecules constructed from smaller repeating units (monomers). There are four primary classes of biological macromolecules: proteins, carbohydrates, lipids, and nucleic acids. They are primarily composed of carbon, hydrogen, oxygen, nitrogen, and phosphorus. == 1. Proteins: The Cellular Workhorse...")

It explains both the remarkable similarities among all living things—originating from a common ancestor—and the staggering diversity of life on Earth. At its core, evolution is simply defined as a change in allele frequencies within a population over successive generations. == 1. Natural Selection and Adaptation == Proposed independently by Charles Darwin and Alfred Russel Wallace, natural selection is th...")

By meticulously cross-breeding pea plants (''Pisum sativum'') and statistically analyzing their traits over multiple generations, Mendel established the core rules of how biological information is passed from parent to offspring. These rules, now known as Mendelian genetics, remain the foundation of classical genetics. =...")

While the diversity of life is immense, all cellular life can be categorized into two fundamental architectural plans: prokaryotic and eukaryotic. == Prokaryotic Architecture: Streamlined Efficiency == Prokaryotes (domains Bacteria an...")
03:1703:17, 26 September 2026 The Central Dogma of Molecular Biology (hist | edit) [7,070 bytes] Bpwhite (talk | contribs) (Created page with "The "Central Dogma" of molecular biology, a framework first proposed by Francis Crick in 1958, describes the fundamental flow of genetic information within a biological system. It states that genetic information moves directionally from DNA, to RNA, and finally to proteins. While modern biology has discovered specific exceptions—such as retroviruses that can transcribe RNA back into DNA—the central dogma remains the foundational model for understanding how cellular...")
