ABSTRACT

The prediction of RNA 3D structure is an important yet challenging

task. Techniques used to predict RNA structure must balance com-

putational expense with desired accuracy. One technique that has

arisen to meet this balance is that of coarse-grained models. Here,

we discuss existing frameworks involving coarse-grained modeling

of RNA 3D structure. Basic RNA structure is first introduced. Then,

the coarse-grained models are divided into two groups: fragment

based and physics based. The models are presented in detail

to understand the advances and limitations of the field. Finally,

conclusions, challenges, and avenues for improvement are tendered,

understanding that coarse-grainedmodeling techniques fill a salient

niche in the field of RNA structure prediction.
