Question

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:

Genomics focuses on the entire set of genes (genome) of an organism, including their structure, function, and evolution. Molecular biology studies biological activity at the molecular level, such as the interactions between DNA, RNA, and proteins. Both fields are centered around genes, genetic variations (differences in DNA sequences among individuals), and biological pathways (series of molecular interactions that perform a specific function in a cell). The development of new laboratory technology is a means rather than the primary focus. The study of global ecosystems is more related to ecology.

Answer:

the study of genes, genetic variations, and biological pathways
