The DNA microarray is a technology that is used to identify whether a specific person's DNA has mutations in genes like BRCA1 and BRCA2 which cause cancer.
Therefore, a microarray assesses the quantity of mRNA transcripts in a sample, A genome-wide perspective of gene expression in cancer can be obtained since thousands of gene fragments can be found on an array.
The idea behind microarrays is that sequences that are complimentary to one another will bind to one another.
Restrictions endonucleases fragment the unidentified DNA molecules, which are then labeled with fluorescent dyes.
These are then given a chance to interact with DNA chip probes.
Chemotherapy has a positive effect on one group while having a negative effect on the other.
Gene-expression microarrays have shown that the two groups' gene-expression patterns differ.
