Question

Explain Microarrays. How Are They Related To Dna?



​

Answer 1

Answer:

A microarray is a laboratory tool used to detect the expression of thousands of genes at the same time. DNA microarrays are microscope slides that are printed with thousands of tiny spots in defined positions, with each spot containing a known DNA sequence or gene.

Answer 2

• A DNA microarray is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome.
• Each DNA spot contains picomoles of a specific DNA sequence, known as probes.
