  1. Period is a gene located on the X chromosome of Drosophila melanogaster. Oscillations in levels of both per transcript and its corresponding protein PER have a period of approximately 24 hours and together play a central role in the molecular mechanism of the Drosophila biological clock driving circadian rhythms in eclosion and locomotor activity. Mutations in the per gene can shorten, lengthen, and even abolish the period of the circadian rhythm.

    When was the period gene first sequenced?The discovery of mutants that altered the period of circadian rhythms in eclosion and locomotor activity (per S and per L) indicated the role of the per gene in the clock itself and not an output pathway. The period gene was first sequenced in 1984 by Michael Rosbash and colleagues.

    What does the per gene look like?Period gene (per) is a crucial gene to test the molecular basis of circadian rhythms in animals. The current page only talks about how per alleles can alter circadian periods. There is no detailed information regarding what the gene looks like, how it works, why it matters to chronobiology and who, and by what means, discovered the gene.

    What are the three phenotypes of the period gene?The period gene and three mutants (perS, perL, and per0) were isolated in an EMS mutagenesis screen by Ronald Konopka and Seymour Benzer in 1971. The perS, perL, and per0 mutations were found to complement each other, so it was concluded that the three phenotypes were due to mutations in the same gene.

    Organisms inherit their genes from their parents. Asexual organisms simply inherit a complete copy of their parent's genome. Sexual organisms have two copies of each chromosome because they inherit one complete set from each parent.

    • Circadian clock
      In Drosophila, per mRNA levels oscillate with a period of approximately 24 hours, peaking during the early subjective night. The per product PER also oscillates with a nearly 24 hour period, peaking about six hours after per mRNA levels during the middle subjective night.[citation neede…
    • Non-circadian
      In addition to its circadian functions, perhas also been implicated in a variety of other non-circadian processes. The mammalian period 2 gene plays a key role in tumor growth in mice; mice with an mPer2 knockout show a significant increase in tumor development and a significan…
