Structural biology

Molecular biology is a branch of science that explores the structure and function of the molecules essential to life, focusing on the interactions between various systems of a cell, including the interrelationship of DNA, RNA, and protein synthesis. It provides insights into the molecular mechanisms of genetic replication, transcription, translation, and cell function, forming the foundation for understanding complex biological processes and disease mechanisms.

molecular biology

Molecular structure refers to the three-dimensional arrangement of atoms within a molecule, which determines its chemical properties and reactivity. Understanding molecular structure is crucial for predicting how molecules interact in chemical reactions and in biological systems.

dynamics of biological macromolecules

Biological macromolecules are large, complex molecules that are critical for life, serving as the building blocks of cells and performing a wide range of functions essential to biological processes. They include proteins, nucleic acids, carbohydrates, and lipids, each with unique structures and roles in cellular activities such as catalysis, genetic information storage, energy provision, and structural support.

biological macromolecules

Proteins are complex macromolecules essential for various biological functions, including catalyzing metabolic reactions, DNA replication, and transporting molecules. They are composed of amino acids linked in a specific sequence, which determines their structure and function.

proteins

Nucleic acids, including DNA and RNA, are essential biomolecules that store and transmit genetic information in all living organisms. They are composed of long chains of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base, enabling the encoding of genetic instructions for the development, functioning, and reproduction of life.
