Question

choose the correct answer. what is the primary focus of genomics and molecular biology? the development of new laboratory technology the study of genes, genetic variations, and biological pathways the study of global ecosystems

Explanation:

• Option 1: Genomics and molecular biology focus on biological molecules/genes, not mainly lab tech development.
• Option 2: Genomics studies genomes (genes, genetic variations), molecular biology studies biological pathways at molecular level (like gene expression, protein interactions), so this matches their focus.
• Option 3: Study of global ecosystems is ecology/ecosystem science, not genomics/molecular biology.

Answer:

the study of genes, genetic variations, and biological pathways
