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).

Effect of mRNA secondary structure in the regulation of gene expression: unfolding of stable loop causes the expression of Taq polymerase in E.
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 (%).
Correlation between protein secondary structures and protein in vitro digestibility and solubility
The experiment used the same data set (including the type of alignment profiles) and secondary structure definition (reduction from eight to three secondary structures) as those employed by Rost and Sander [17], and Jung-Ying Wang [18].
With that limitation, a maximum number of four to six primer pairs must be carefully designed to match annealing temperature and oligonucleotide size while minimizing secondary structures, complementary 3' ends, and cross-reactivity to non-specific targets.
