How do genomics, proteomics, and systems biology collectively contribute to a comprehensive understanding of biological systems, as described in the text?
A: Genomics identifies all genes and their regulatory sequences, proteomics analyzes all proteins and their functions, and systems biology integrates these 'parts' to model the dynamic behavior of whole biological systems.
B: Genomics focuses on gene expression in individual cells, while proteomics studies protein synthesis rates, and systems biology applies these to clinical diagnoses only.
C: All three fields primarily aim to discover new drugs by studying single genes and proteins in isolation.
D: Genomics and proteomics are older disciplines that have been replaced by systems biology, which is the only current method for biological research.
Explanation
The text explains that genomics and proteomics provide the 'catalogs of genes and proteins' which are the 'parts' that contribute to cellular and organismal operation. Systems biology then shifts attention 'from the individual parts—genes and proteins—to their functional integration in biological systems,' aiming 'to model the dynamic behavior of whole biological systems'.
