When dna microarrays containing asos are used to genotype snps, what form of dna constitutes the probe molecules?
umka2103 [35]

DNA microarray uses 20-40 sequence-specific oligonucleotides as probes to identify the SNP.

DNA microarray is a technique used to measure gene expression. It works on the principle of hybridization.

The genome of the reference organism is attached to a solid surface (silicon chip). The DNA of the test organism is made to hydride with the reference organism. Depending on the level of hybridization the fluorescent or the chemiluminescent is measured to identify the expression.

Single nucleotide polymorphism (SNP) is the change in the single nucleotide of the genome. SNPs can be identified with the help of DNA microarray.
