Genomics involves the sequencing, assembly, and annotation of genomes, enabling the identification of genes, regulatory elements, and variations associated with diseases or traits. Proteomics, on the other hand, deals with the identification, quantification, and functional characterization of proteins. Techniques like mass spectrometry produce vast amounts of data that are analyzed using bioinformatics pipelines to understand protein interactions, post-translational modifications, and their roles in cellular processes.

This approach integrates data from various sources, including genomics, transcriptomics, proteomics, and metabolomics, to build comprehensive models of biological pathways and networks. Computational tools are used for network analysis, simulation, and modeling to predict system behavior under different conditions, offering insights into complex phenomena like disease progression or drug response.

Key tasks in bioinformatics include database management (e.g., GenBank, UniProt), sequence alignment (e.g., BLAST), phylogenetic analysis, gene expression analysis, and the development of algorithms for predicting protein structure and function. It provides the essential tools and methodologies that underpin most computational biology research.

Deep learning models, in particular, are showing remarkable success in areas like drug discovery, protein structure prediction (e.g., AlphaFold), and image analysis of biological samples. The ability to train models on vast datasets allows for the discovery of complex relationships that might be missed by traditional statistical methods.

Computational approaches are essential for processing and interpreting the high-dimensional data generated by single-cell RNA sequencing (scRNA-seq), single-cell ATAC-seq, and other single-cell omics technologies. This includes tasks like cell clustering, trajectory inference, and differential expression analysis at the single-cell level.
