Functional analysis directly measures the protein activity levels in the cell

Pathway enrichment analysis detects overrepresented pathways, such as metabolic or signaling pathways, in the dataset.

Functional analysis predicts secondary structures of RNA molecules to determine their stability

Gene Ontology (GO) analysis identifies biological processes, molecular functions, and cellular components associated with differentially expressed genes

Differential expression analysis is used to group genes with similar expression patterns and infer their functions indirectly

Functional analysis applies to a specific gene expression across all the sample of patients
