sekvensere

Sekvensere, in Norwegian, refers to devices or software that perform sequencing. The term is used in two major domains: molecular biology, where sequencing determines the order of nucleotides in DNA or RNA, and music technology, where sequencing plans and triggers sequences of musical events. In both contexts, sequencers control time-structured information and produce interpretable output data.

In molecular biology, sequencing instruments convert biological material into digital sequence data. The field has evolved from Sanger sequencing (first generation) to next-generation sequencing (NGS) platforms that generate millions to billions of reads in parallel. Major NGS technologies include short-read platforms (e.g., Illumina) offering high throughput and accuracy, and long-read platforms (e.g., PacBio SMRT, Oxford Nanopore) delivering longer reads with different error profiles but better resolution of structural variations. Typical workflows combine library preparation, sequencing, and bioinformatic analysis to assemble genomes, identify variants, or quantify transcripts. Sequencers are central to research, clinical genomics, agriculture, and forensics. Factors such as cost, runtime, read length, and per-base accuracy influence platform choice.

In music technology, sequencers are devices or software that store and trigger musical events on a time grid. They can be hardware step sequencers, which fire notes in fixed steps, or software sequencers integrated into digital audio workstations. Features include tempo control, pattern length, polyphony, MIDI or CV/Gate compatibility, recording, and quantization. Sequencers enable complex rhythms and melodic sequences in electronic and experimental music, often without simultaneous live performance.

Although the two domains share a name, the underlying technologies and goals differ, with both relying on precise timing and data handling to produce reproducible results.
