The term "gene array system" refers to a type of technology used in molecular biology research that allows scientists to analyze the expression of multiple genes at once. Some synonyms for this term include microarray technology, gene chip technology, gene expression analysis, and transcriptomics. Depending on the specific technology or application, other terms that may be used include DNA microarrays, oligonucleotide arrays, cDNA arrays, and high-throughput gene expression profiling. Regardless of the terminology used, gene array systems are a critical tool in modern biology research, allowing scientists to rapidly gather information about the expression of thousands of genes in a single experiment.
