2. 2
   noununcountable

   The procedure of determining the order of nucleotides in a stretch of DNA, or of amino acids in a protein.

   Whole-genome sequencing has become affordable enough for routine clinical use.

   The lab completed protein sequencing to identify the unknown enzyme.

   Note

   A laboratory term that usually comes with a modifier naming what is being read. Protein sequencing works out the chain of amino acids in a polypeptide, and gene sequencing works out the run of nucleotides in DNA. Both are cases of one idea: finding the order of the building blocks in a biological polymer. As a count noun, with the plural sequencings, it names individual runs of the procedure.

3. 3
   verb

   Present participle of sequence.

   Researchers are sequencing thousands of genomes for the new study.

   The team spent months sequencing the bacterial genome.

   Note

   One spelling does two jobs. After be it forms the progressive (they are sequencing the genome), and on its own it works as a verbal noun. Nearly every use takes a direct object, whether the thing put in order is a schedule, a protein, or a track built on a sequencer. The intransitive use, meaning to move through a series, is uncommon. Without an object in view, the word is usually the noun for arrangement.
