How Do Gene Expression Arrays Differ from Comparative Genome Hybridization

question 27

Multiple Choice

• A) CGH arrays detect gain or loss of DNA regions; gene expression arrays detect changes in gene expression.
• B) CGH arrays can interrogate hundreds of genes, while gene expression arrays test thousands.
• C) CGH arrays are simpler to perform than gene expression arrays.
• D) CGH arrays require co-hybridization with comparative reference nucleic acid, while gene expression arrays do not.
