Abstract

We offer a high-level overview of multiscale molecular visualisation methods, concentrating on issues, difficulties, and tasks specific to particular applications. We give a comprehensive overview of the fundamentals of molecular visualisation and list several domain-specific challenges that motivate this research. These tasks in turn form the basic framework for the ensuing survey. We start out by talking about techniques that help with visual inspection of molecular dynamics simulations (Kushnir MM et al., 2008). We focus on visual abstraction and temporal aggregation in particular. In the second section, we review multiscale methods for designing, analysing, and manipulating DNA nanostructures as well as associated ideas for abstraction, scale transition, scale-dependent modelling, and navigating the resulting abstraction spaces. We provide methods that facilitate interactive exploration within huge structural biology assemblies that are as large as bacterial cells in the third section of the review. We go through basic rendering methods as well as strategies for element instantiation, visibility control, visual direction, camera control, and depth perception support. We conclude the survey by providing key research challenges in the area and a succinct list of significant tools that implement many of the discussed approaches (Aldrimère M et al., 2012).

INTRODUCTION

Data visualisation is a method assisted by computers for visually presenting complicated digital information to users. Visualisation is frequently implemented as a pipeline, in which the digital data are transformed at various stages before being represented visually on the computer screen. To limit the total amount that needs to be handled, digital data are filtered in the first step based on relevancy. In order to create a representation with a high expressive value, data can also be aggregated, derived, and subsampled. The data are then mapped to geometric primitives with specific optical or visual characteristics in the following stage. In the rendering stage, an image is finally created, displaying the visual representation on the screen (Elmlinger MW et al., 2002).

The primary characteristic of computer visualisation software is interactivity, which enables users to change structural images graphically via a graphical user interface. A user can inspect any part of the structure in great detail, move, rotate, and zoom an atomic model on a computer screen with the click of a mouse button, as well as sketch the model in numerous shapes and colours. Additional modifications could involve fitting a ligand to an enzyme active site using docking exercises or altering the shape of a structure through protein modelling (Elmlinger MW et al., 2005).

DISCUSSION

Proteins are significant biological macromolecules that are frequently regarded as the basic building blocks of a cell and play a crucial role in a variety of cell processes. A protein's function is extremely specialised and is reliant on the chemical it binds. There are four categories for protein structure: primary, secondary, tertiary, and quaternary. Following their initial formation as a linear chain of amino acids, these molecules fold into secondary, tertiary, and quaternary structures. A protein can have alpha helices, beta pleated sheets, or loops as its secondary structures (Soldin OP et al., 2005). The function of a given protein is greatly influenced by certain areas of the protein that remain constant over the course of evolution and are known as motifs. Each protein is composed of a long chain of amino acids that fold into a three-dimensional form. Organic substances known as amino acids have a hydrogen atom, a carbon atom, two functional groups, and R group on the side chain. The human body has over 20 amino acids with a range of R groups. Peptide bonds are what connect amino acids to one another. When the carboxyl group of one amino acid is joined to the amino group of another molecule by a covalent bond, a peptide bond is created (Owen WE et al., 2010). A protein's main structure is made up of a linear arrangement of amino acids. It is produced as mRNA is being translated from DNA. Deoxyribonucleic acid, also known as DNA, is the genetic component that contains all of the genetic data necessary for the growth and maintenance of all biological activities. Four different types of bases are used to store the information as genetic coding. They are thymine (T), adenine (A), guanine (G), and cytosine (C). Only one base pair separates RNA from DNA; in RNA, uracil (U) replaces thymine. mRNA (messenger RNA) is an RNA molecule that develops from the transcription of DNA. Thymine is changed to uracil during the transcription process, which converts DNA to mRNA (Konforte D et al., 2013).

To interactively display a single macromolecule was computationally difficult in the early days of computer graphics. Simple methods have been used for a while to represent molecular structures as mesh geometry that may be seen using accelerated graphics programmes (Yang L et al., 2005). For the majority of the analytical jobs back then, such a representation was enough for interactively displaying merely a few hundred to thousands of atoms. The aforementioned methods are inadequate for representations of dynamic molecules. It would be difficult to extract the mesh, and meshing the complete dynamics sequence would need too much memory. Thus, up until recently, single-scale structures and dynamics dominated molecular visualisation (Davis GK et al., 2006).

CONCLUSION

In today's scientific literature, textbooks, and educational materials, molecular visualisation is essential. It offers crucial support for outlining findings, thinking through, and developing molecular structure-related ideas. Thanks to sophisticated software tools that provide a tremendous benefit to the scientific community, tools for visual study of structural data are now readily available on a wide range of platforms. These technologies are frequently created by combining the fields of computer science, biology, and chemistry (Carel JC et al., 2009).
