sec·on·dar·y struc·ture

the localized arrangement in space of regions of a biopolymer; often these types of structures are regular and recurring along one dimension, for example, the α-helix often found in proteins.

secondary structure

n.
The three-dimensional structure of the polypeptide backbone of a protein (such as alpha helix, beta sheet, and coil patterns), or the sugar-phosphate backbone of a nucleic acid (such as the double helix pattern of DNA).

In this study, when the barrel temperature increases from 45-105[degrees]C, secondary structures play an important role in the TIU level; as the materials' moisture content increases from 5 -25%, NSI and PDI were determined by the turn (%), and TIU was changed by the [beta]-sheet (%) and unordered (%); when the nozzle diameter was changed from 10-28 mm, the NSI was affected by the turn (%).
In the next step, the secondary structures were predicted from sequences of 50 pre-miRNAs from set S2.

Sample issues can often be satisfactorily addressed through choice of flanking sequences around site of diagnostic interest Oligonucleotide Design Specificity to diagnostic target site, especially challenging for single nucleotide polymorphism (SNP) or mutational analysis Off-target cross-reactivity and non-specific amplification, due to primer-sequence interactions and primer-primer/primer-probe interactions, leading to false positives Secondary structures, leading to both false negatives and false positives Table 2.
In this paper, we would investigate protein secondary structures based on protein sequences.
