spacer sequence

The genetic material on a chromosome that separates actively transcribed genes. It may make up the largest part of the genome of some eukaryotic organisms and often consists of tandem repeats of DNA. Synonym: spacer DNA

terminator sequence

In genetics, a specific series of nucleotides that instructs a cell to stop transcribing a gene.

sequential analgesia

I started by taking the Bakhtinian concept of heteroglossia and discourse and its sequentiality as a starting point and as a unit of analysis.
We summarize these questions as follows: (1) How do sequentiality and information about previous contributions in a sequence affect the contributions of subjects who have to decide later in the sequence?
The causal inference can be approximated by a visual analysis of the patterns of sequentiality between peaks in media attention (lines) and peaks in government action (dots).
The majority of narratological models explicitly or implicitly rest on the premise that narrativity is constituted by the combination and interaction of two different dimensions, of sequentiality and mediacy: a sequence of incidents (together with existents such as figures and setting) evolving in time, on the one hand (termed "histoire" by Genette, "story" by Chatman) and, on the other, the structured representation and communication of such a sequence by a mediator in a semiotic medium and from a particular position (Genette's "recit", Chatman's "discourse").
Symmetry versus sequentiality related to prior training, sequential dependency of stimuli, and verbal labeling.
Thus, although one can certainly talk about sequentiality, it would not be correct to characterize it as linear.
This applies to Brakhage as well, in large part because there is probably no greater influence on Brakhage than Stein, at least in terms of thinking of alternatives to narrative sequentiality as the foundation of consciousness.
enabling factors) that affect communication efficiency: copresence, visibility, audibility, cotemporality, simultaneity, sequentiality, reviewability, and revisability (see Table 2).
In addition, they also allow the analysis of the relations between these behaviours, such as sequentiality, association and covariation.
Future research should use longitudinal designs in which sequentiality and directionality can be empirically determined.
Both sequentiality and change are suspended in the activity of reflection.
It allows for a sharp description of frictions that private information and sequentiality of transactions imposed on the provision of insurance against preference shocks.
