1·To assess gene expression in each small bit of tissue, researchers expose its RNA to a gene chip, or DNA microarray.
为了评价每小片组织中的基因的表达情况，研究人员将它的RNA暴露给一个基因芯片，或者DNA阵列。
2·A new device called the microarray, a small chip coated with DNA sequences, can simultaneously analyze many more spots on the chromosomes.
一种叫微阵列(microarray)的新仪器，即一块覆盖着DNA序列的小芯片，可以同时分析染色体上的很多点。
