Genotyping | DNA | Assessment of variability in DNA sequence in the genome | None | No |
Epigenomics | Epigenetic modifications of DNA | Assessment of factors that regulate gene expression without changing DNA sequence of the genome | Low/moderate | Probable |
Gene expression profiling | RNA | Assessment of variability in composition and abundance of the transcriptome | High | Yes |
Proteomics | Proteins | Assessment of variability in composition and abundance of the proteome | High | Yes |
Metabolomics | Small molecules | Assessment of variability in composition and abundance of the metabolome | High | Yes |
