Which of the following techniques involves hybridizing a cDNA sample to a chip containing thousands of single-stranded DNA sequences, allowing one to study the expression of thousands of genes simultaneously? A) PCR
B) Southern blot
C) FISH
D) Agarose gel electrophoresis
E) DNA microarray

Option E.

DNA micro array.

Explanation:

DNA microarray is a technique that involves hybridizing cDNA into a chip that contains thousands of single stranded DNA sequences. This technique enables one to study expression of thousands of genes at the same time.looks for extra (duplicated) or missing (deleted) chromosomal segments, sometimes called copy number variants (CNVs).

DNA microarrays are microscope slides which are printed with thousands of tiny spots in specific different positions, and each of the spots contain a known DNA sequence or gene.

primary use of DNA microarrays is transcriptional profiling.

The basic principle behind the DNA microarray is “ nucleic acid hybridization.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
