Question

Quizplus · Accepted Answer

DNA chip technologies (also known as microarray analysis) are used to examine gene expression and show transcriptional patterns in an organism during different times of development or under various conditions. This technology involves placing tiny amounts of DNA sequences onto a small surface, which can then be used to detect the presence of complementary DNA in a sample. This information can be used to study gene expression, identify biomarkers for various diseases, and develop personalized medicine. While DNA chips can provide information about an individual's genetic predisposition to certain diseases, they cannot predict with certainty whether someone will get cancer. They also cannot clone DNA, make transgenic plants, or inhibit transcription of disease genes.
