  2. Molecular machine - Wikipedia

    en.wikipedia.org/wiki/Molecular_machine

    Naturally occurring or biological molecular machines are responsible for vital living processes such as DNA replication and ATP synthesis. Kinesins and ribosomes are examples of molecular machines, and they often take the form of multi-protein complexes. For the last several decades, scientists have attempted, with varying degrees of success ...

    This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...

  5. Molecular motor - Wikipedia

    en.wikipedia.org/wiki/Molecular_motor

    Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work ; for example, many protein -based molecular motors harness the chemical free energy ...

  6. Ribosome - Wikipedia

    en.wikipedia.org/wiki/Ribosome

    The ribosome is a complex cellular machine. It is largely made up of specialized RNA known as ribosomal RNA (rRNA) as well as dozens of distinct proteins (the exact number varies slightly between species). The ribosomal proteins and rRNAs are arranged into two distinct ribosomal pieces of different sizes, known generally as the large and small ...

  7. Biological system - Wikipedia

    en.wikipedia.org/wiki/Biological_system

    On the origin and impact of information in the average evolution. Includes how life forms and biological systems originate and from there evolve to become more and more complex, including evolution of genes and memes, into the complex memetics from organisations and multinational corporations and a "global brain", (Yves Decadt

  8. Synthetic biology - Wikipedia

    en.wikipedia.org/wiki/Synthetic_biology

    Synthetic biology (SynBio) is a multidisciplinary field of science that focuses on living systems and organisms, and it applies engineering principles to develop new biological parts, devices, and systems or to redesign existing systems found in nature.

  9. Protein complex - Wikipedia

    en.wikipedia.org/wiki/Protein_complex

    Kinesin is a protein functioning as a molecular biological machine. It uses protein domain dynamics on nanoscales. A protein complex or multiprotein complex is a group of two or more associated polypeptide chains. Protein complexes are distinct from multidomain enzymes, in which multiple catalytic domains are found in a single polypeptide chain ...
