Opus clavicembalisticum is a work for solo piano, notable for its length and difficulty, composed by Kaikhosru Shapurji Sorabji and completed on 25 June 1930. [1]At the time of its completion, it was the longest piano piece in existence, taking around 4–4½ hours to play, depending on tempo.
There are many examples of musics generated by this software, both by designer [27] and by others. [28] Several people have composed musics using protein structure, and several students and professors have used music as a method to study proteins. [13] The recording Sounds of HIV is a musical adaptation of the genetic material of HIV/AIDS. [29]

ORGAN 2 /ASLSP (As Slow as Possible) is a musical piece by John Cage and the subject of the second-longest-lasting (after Longplayer) musical performance yet undertaken.

Examples include circannual or annual cycles that govern migration or reproduction cycles in many plants and animals, or the human menstrual cycle. Ultradian rhythms , which are cycles shorter than 24 hours, such as the 90-minute REM cycle , the 4-hour nasal cycle , or the 3-hour cycle of growth hormone production.
The evolution of biological complexity is one important outcome of the process of evolution. [1] Evolution has produced some remarkably complex organisms – although the actual level of complexity is very hard to define or measure accurately in biology, with properties such as gene content, the number of cell types or morphology all proposed as possible metrics.
Examples of highly conserved sequences include the RNA components of ribosomes present in all domains of life, the homeobox sequences widespread amongst eukaryotes, and the tmRNA in bacteria. The study of sequence conservation overlaps with the fields of genomics, proteomics, evolutionary biology, phylogenetics, bioinformatics and mathematics.
