  2. Lennard-Jones potential - Wikipedia

    en.wikipedia.org/wiki/Lennard-Jones_potential

    The Lennard-Jones potential is a simple model that still manages to describe the essential features of interactions between simple atoms and molecules: Two interacting particles repel each other at very close distance, attract each other at moderate distance, and eventually stop interacting at infinite distance, as shown in the Figure.

  3. Contact mechanics - Wikipedia

    en.wikipedia.org/wiki/Contact_mechanics

    Stresses in a contact area loaded simultaneously with a normal and a tangential force. Stresses were made visible using photoelasticity.. Contact mechanics is the study of the deformation of solids that touch each other at one or more points.

  4. Lambda phage - Wikipedia

    en.wikipedia.org/wiki/Lambda_phage

    It is not generally appreciated that the 12 bp lambda cohesive ends were the subject of the first direct nucleotide sequencing of a biological DNA. [6] Lambda phage DNA injection into the cell membrane using Mannose PTS permease (a sugar transporting system) as a mechanism of entry into the cytoplasm

  5. Cell adhesion - Wikipedia

    en.wikipedia.org/wiki/Cell_adhesion

    Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...

  6. Integration host factor - Wikipedia

    en.wikipedia.org/wiki/Integration_host_factor

    HU and integration host factor function as auxiliary proteins in cleavage of phage lambda cohesive ends by terminase is an academic journal written by the Department of Molecular Genetics. In their article, they created isogenic strains of E.coli that were lacking HU or integration host factors to test whether bacteriophage would grow under ...

  7. Sticky and blunt ends - Wikipedia

    en.wikipedia.org/wiki/Sticky_and_blunt_ends

    The simplest DNA end of a double stranded molecule is called a blunt end. Blunt ends are also known as non-cohesive ends. In a blunt-ended molecule, both strands terminate in a base pair. Blunt ends are not always desired in biotechnology since when using a DNA ligase to join two molecules into one, the yield is significantly lower with blunt ...

  8. Lambda function - Wikipedia

    en.wikipedia.org/wiki/Lambda_function

    Dirichlet lambda function, λ(s) = (1 – 2 −s)ζ(s) where ζ is the Riemann zeta function; Liouville function, λ(n) = (–1) Ω(n) Von Mangoldt function, Λ(n) = log p if n is a positive power of the prime p; Modular lambda function, λ(τ), a highly symmetric holomorphic function on the complex upper half-plane

  9. Zero-point energy - Wikipedia

    en.wikipedia.org/wiki/Zero-point_energy

    Zero-point energy (ZPE) is the lowest possible energy that a quantum mechanical system may have. Unlike in classical mechanics, quantum systems constantly fluctuate in their lowest energy state as described by the Heisenberg uncertainty principle. [1]
