RIP

• R.I.P.

Borrowed from Latin RIP (requiescat in pace) and an initialism of English rest in peace.

• IPA^(key): /aː(ɹ) aɪ ˈpiː/

RIP

1. Initialism of rest in peace.

• The phrase is never used in reference to actual sleep or rest for the living; it refers only to the dead.
• Typically found as an epitaph on a tombstone or in an obituary (and hence on graves in Halloween decorations, cartoons, etc.).
• The phrase is sometimes used as an epithet when referring to a deceased person, as in “This university was founded by Thomas Jefferson, RIP.”
• Also used as an indirect way of stating that someone or something is (literally or figuratively) dead.

• RHIP

RIP

1. Routing information protocol, a dynamic routing protocol used in local and wide area networks.

Originally coined in Selker et al. (1987) as an acronym for rearrangement induced premeiotically, which was later renamed repeat-induced point mutation in Cambareri et al. (1989).

• IPA^(key): /ɹɪp/

RIP (uncountable)

1. (molecular biology) Repeat-induced point mutation, a process by which both copies of duplicated sequences are mutated.
   • 1987 December 4, Eric U. Selker; Edward B. Cambareri; Bryan C. Jensen; Kenneth R. Haack, “Rearrangement of duplicated DNA in specialized cells of Neurospora”, in Cell, volume 51, number 5, page 750:

     The RIP process can be extremely efficient. A linked duplication of 6 kb of Neurospora DNA, whose elements were separated by 7.5 kb of bacterial and unique Neurospora sequences, never survived a cross unrearranged.

   • 1989 June 30, Edward B. Cambareri; Bryan C. Jensen; Eric Schabtach; Eric U. Selker, “Repeat-Induced G-C to A-T Mutations in Neurospora”, in Science, volume 244, number 4912, page 1573:

     Thus, the RIP process results in point mutations, consistent with the results from the heteroduplex analyses. On the basis of this information, we suggest changing the name of the phenomenon from "rearrangement induced premeiotically" to "repeat-induced point mutation."

   • 2003 April 24, James E. Galagan et al., “The genome sequence of the filamentous fungus Neurospora crassa”, in Nature‎, volume 422, page 860:

     To investigate the impact of RIP on protein families in Neurospora, genes were clustered into ‘multigene families’ on the basis of an all versus all comparison of protein sequences (see Methods).
