It can be used when referring to a specific order or arrangement of items or events, often in a context where more information follows.
Example: "The experiment requires a certain sequence and timing of the chemical reactions to achieve the desired results."
Alternatives: "a specific order and" or "a particular arrangement and".
But some calculations must be done in a certain sequence, and part two cannot be done before part three.
Dr. Adleman, a professor at the University of Southern California, set up his problem by synthesizing DNA in a certain sequence and then letting DNA molecules react in a test tube so they ultimately produce a molecule whose sequence is the answer to the problem.

The other one I use out of the Wechsler is called … visual memory span…where you have a card with dots on it and you touch the dots in a certain sequence and they've got to touch the dots in the same sequence, so there's no language, once you've got the trick across.
The choice for a certain sequencing and analysis approach was irrespective of disease subtype or expected genetic complexity of the individual patients.
The goal of mutual information consists in finding correlations between the variation of residues at a certain sequence position and the variation of ligand properties.

"You get a certain sequence of pieces in Tetris, and that's out of your control, but what you do with them is in your control.
The seminal work in information theory is Claude Shannon's 1948 paper "A Mathematical Theory of Communication," which is mainly about the efficiency with which a certain sequence (say, a set of dots and dashes) can be transmitted and reproduced.
Sequence comparison of these engineered lipocalins with the wild-type BBP revealed that all of the 16 randomized positions carried an amino acid exchange and that a certain sequence pattern had been selected, thus pointing toward a peculiar mode of structural interaction.
