Researchers are looking for better treatments for breast cancer. For a particular DNA microarray assay (DNA chip), cDNA has been made from the mRNAs of a dozen patients' breast tumor biopsies. The researchers will be looking for a

Question

Quizplus · Accepted Answer

The researchers will be looking for a pattern shared among some or all of the samples that indicates gene expression differing from control samples. This is because they want to identify any genes that are being expressed differently in breast cancer cells compared to normal cells. This information can help identify potential targets for new treatments or diagnostics. Option A is too specific as researchers are not necessarily looking for just one gene. Option B is also too specific and not necessarily indicative of breast cancer. Option D is not relevant to the question. Option E is not the best choice as the researchers are looking for differences in gene expression between breast cancer cells and normal cells, not just a match with control samples.
