Multiple choice

Which among the following does not characterises the process of DNA microarray?

  1. A DNA microarray is a collection of microscopic DNA spots attached to a solid surface.

  2. Probe-target hybridization is usually detected and quantified by detection of fluorophore, platinum, or chemiluminescence-labeled targets.

  3. DNA microarray experiment can accomplish many genetic tests in parallel.

  4. DNA microarrays can be used to detect single nucleotide polymorphisms.

  5. DNA microarrays involves the hybridization between two DNA strands.
