  2. Luria–Delbrück experiment - Wikipedia

    en.wikipedia.org/wiki/Luria–Delbrück_experiment

    (B) If mutations arise spontaneously during cell divisions prior to plating, each plate will have a highly variable number of mutants. The Luria–Delbrück experiment (1943) (also called the Fluctuation Test ) demonstrated that in bacteria , genetic mutations arise in the absence of selective pressure rather than being a response to it.

  3. Epigenetic clock - Wikipedia

    en.wikipedia.org/wiki/Epigenetic_clock

    An epigenetic clock is a biochemical test that can be used to measure age. The test is based on modifications that change over time and regulate how genes are expressed. Typically, the test examines DNA methylation levels, measuring the accumulation of methyl groups to one's DNA molecules, or more recently, based on the histone

  4. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    Genomic DNA is tightly and orderly packed in the process called DNA condensation, to fit the small available volumes of the cell. In eukaryotes, DNA is located in the cell nucleus, with small amounts in mitochondria and chloroplasts. In prokaryotes, the DNA is held within an irregularly shaped body in the cytoplasm called the nucleoid. [97]

  5. Single-molecule real-time sequencing - Wikipedia

    en.wikipedia.org/wiki/Single-molecule_real-time...

    The DNA sequencing is done on a chip that contains many ZMWs. Inside each ZMW, a single active DNA polymerase with a single molecule of single stranded DNA template is immobilized to the bottom through which light can penetrate and create a visualization chamber that allows monitoring of the activity of the DNA polymerase at a single molecule level.

    A nuclear profile is simply this strip or slice that is taken from the nucleus. Each nuclear profile contains genomic windows, which are certain sequences of nucleotides - the base unit of DNA. GAM captures a genome network of complex, multi enhancer chromatin contacts throughout a cell. [21]

  8. Genotyping - Wikipedia

    en.wikipedia.org/wiki/Genotyping

    Genotyping is the process of determining differences in the genetic make-up of an individual by examining the individual's DNA sequence using biological assays and comparing it to another individual's sequence or a reference sequence.

  9. Virtual Cell - Wikipedia

    Virtual Cell is an advanced software platform for modeling and simulating reaction kinetics, membrane transport and diffusion in the complex geometries of cells and multicellular tissues. VCell models have a hierarchical tree structure.
