Question

Quizplus · Accepted Answer

The essential contribution of genomics that makes microarrays possible is the knowledge of which DNA sequences to synthesize for the array. Microarrays require the synthesis of specific DNA sequences, and genomics research has allowed us to identify and characterize many genes and their sequences. Therefore, the knowledge of these DNA sequences enables researchers to synthesize them for use in microarray experiments.
