Source: Peiman Shahbeigi-Roodposhti and Sina Shahbazmohamadi, Biomedical Engineering Department, University of Connecticut, Storrs, Connecticut A scanning electron microscope (SEM) is an instrument that uses an electron beam to nondestructively image and characterize conductive materials in a vacuum. As an analogy, an electron beam is to the SEM as light is to the optical microscope. The difference is that the electron microscope yields images of much higher resolution and magnification. The...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University How do people find objects in cluttered visual scenes? Think, for example, of looking for keys on a messy desk, finding the ripest-looking fruit at the grocery store, locating your car when you can’t quite remember where you parked it, or finding an old friend at an airport exit gate. Clearly, an understanding of visual perception is going to play a role in any answers, and more specifically, an understanding of visual attention...

This video presents synthetic biology and its role in bioengineering. Synthetic biology refers to the methods used to genetically modify organisms in order to make them capable of producing large quantities of a product. This product could be a protein that the cell already makes or a new protein that has been encoded in a newly-inserted DNA sequence. Here, we discuss how an organism's genetic material is modified using transformation or transfection. Then, the process is shown in the...

2019
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials. Ecosystems also perform critical services, such as purifying our air and water. A large body of evidence indicates that such ecosystem services depend on biodiversity. Furthermore,...

A notable feature of corporations is the transferability of shares, enabling shareholders to sell or transfer their ownership stakes without impacting the corporation's operations. This ease makes investment and liquidity simpler, as demonstrated by the dynamic trading of Apple Inc. shares on the stock market. Corporations benefit from centralized management, typically overseen by a board of directors and executive officers. This structure allows for specialized decision-making, enhancing the...
FAQs
Biological functions emerge when proteins, nucleic acids, lipids, carbohydrates, and small molecules interact in coordinated ways. These interactions can enable catalysis, regulate cellular activity, convert energy, or preserve biological information. Examining the relationships among these molecular components allows biochemists to connect changes in structure with changes in function rather than studying each molecule in isolation.
Molecular structure influences how a component participates in biochemical processes. Structural differences can alter interactions among proteins, nucleic acids, lipids, carbohydrates, and small molecules, which may change catalysis, regulation, energy conversion, or information storage. This structure-function relationship gives researchers a framework for interpreting how molecular changes affect cellular behavior and biological performance.
Homeostasis depends on coordinated molecular regulation within living systems. Interactions among biochemical components help control cellular processes, balance energy-related activities, and adjust functional responses as conditions change. Studying these regulatory relationships shows how cells maintain stable operation and provides context for understanding what happens when molecular control becomes disrupted.
Researchers can examine molecular structures and their functions to identify alterations associated with disease. Comparing normal and changed biochemical characteristics may reveal disrupted regulation, impaired catalysis, altered energy conversion, or problems in information storage. These connections help translate molecular observations into biological explanations and support the development of diagnostics and drug-related investigations.
Biochemical analysis supports biotechnology, drug development, diagnostics, and broader studies of living systems. By linking molecular characteristics to function, researchers can investigate how biological processes operate, recognize changes relevant to disease, and evaluate molecular relationships across organisms. The resulting knowledge provides a foundation for developing useful biological technologies and interpreting disease-related findings.
Shared or differing molecular characteristics can provide information about relationships among organisms. Researchers analyze biological features by comparing components and functions linked to proteins, nucleic acids, lipids, carbohydrates, and small molecules. These comparisons connect biochemical evidence with evolutionary analysis, helping place organisms in a broader biological context while preserving the importance of molecular structure and function.
