    Genetic theories of aging propose that aging is programmed within each individual's genes. According to this theory, genes dictate cellular longevity. Programmed cell death, or apoptosis, is determined by a "biological clock" via genetic information in the nucleus of the cell. Genes responsible for apoptosis provide an explanation for cell ...

    en.wikipedia.org/wiki/Biological_clock

    Circadian clock, a molecular mechanism that results in a circadian rhythm in a living organism; Circadian rhythm, biological process that displays an oscillation about 24 hours, such as the human sleep-wake cycle (the "body clock") Epigenetic clock, a set of DNA sites whose methylation levels can be used to measure aging throughout the body

  4. 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 they can use DNA methylation levels, measuring the accumulation of methyl groups to one's DNA molecules, or more recently, based on the histone

  5. Chronobiology - Wikipedia

    en.wikipedia.org/wiki/Chronobiology

    Overview, including some physiological parameters, of the human circadian rhythm ("biological clock"). Chronobiology is a field of biology that examines timing processes, including periodic (cyclic) phenomena in living organisms, such as their adaptation to solar- and lunar-related rhythms. [1] These cycles are known as biological rhythms.

    en.wikipedia.org/wiki/Biological_rhythm

    Biological rhythms are repetitive biological processes. [1] Some types of biological rhythms have been described as biological clocks. They can range in frequency from microseconds to less than one repetitive event per decade. Biological rhythms are studied by chronobiology.
