Thus, the secondary structures assignment is an essential step for studying protein architecture, folding and for the prediction of 3D protein structure.
Genetic linkage maps are an essential resource for studies on genome structure, genome evolution, and for identification of Mendelian components of QTLs [ 13].
Signing of the latter is essential for study inclusion.
Fluorescence-activated cell sorting (FACS) is an essential tool for studies requiring isolation of distinct intestinal epithelial cell populations.
Multiphoton fluorescence imaging of tissues offers an essential tool for studying biological systems.
Infrared astronomical spectroscopy is an essential tool for studying these earliest epochs and Simcoe has been active in developing new instrumentation toward this end.
Aromatase inhibition is also an essential tool for studying the role of estrogens in the adult, or during development.
Induced pluripotent stem cells (iPSCs) are an essential tool for studying cellular differentiation and cell types that are otherwise difficult to access.
Accurate determination of the wheel rail contact forces and moments is an essential requirement for studying the wheel rail contact mechanics.
Fig trees have become an essential model for studies on mutualism (Janzen [1979]; Frank [1985]), sex ratio theory (Herre [1985]; Weiblen [2002]), and coevolution processes (Anstett et al. [1997]; Cook and Rasplus [2003]).
To develop mathematical models and estimate their parameters are an essential issue for studying dynamic behaviors of biological systems which include metabolic networks, genetic regulatory networks and signal transduction pathways, under perturbation of external stimuli.
