Selected:
- can help in development of effective medications
- can help explain genetic diseases
- composed of about 19,000 genes

Brief reasons:
- Knowledge of the human genetic code (genome) underlies pharmacogenomics and precision medicine, so it can guide development of more effective drugs.
- Genetic sequence information is essential for identifying mutations and mechanisms that cause genetic diseases.
- The human genome contains roughly 19,000–20,000 protein‑coding genes.

Not selected:
- "can only help understand human genetics" — incorrect because genomic data are useful for many applications beyond just understanding genetics (medicine, forensics, anthropology, etc.).
- "composed of 23 chromosomes" — misleading: humans have 23 chromosome types in a haploid set (gametes) but 46 chromosomes (23 pairs) in typical somatic cells.
