WebHow does array CGH work? A microarray works by exploiting the ability of a DNA molecule (or strand) to bind specifically to, or hybridise to, another DNA molecule (strand). The DNA in our cells is arranged as a double helix (see Figure 2) in which the two strands of DNA are bound (‘paired’) together by bonds between the base pairs (bps). WebIn a way, microarray analysis might be thought of as a glorified dot-blot analysis – known DNA sequences immobilized on a solid support hybridize cDNA that represents the RNA being produced by the cell at the moment of lysis. cDNA sequencing data mirror transcript complexity and abundance within a sample. biography of talat mahmoodWebFeb 1, 2024 · A DNA microarray is a tool used to determine whether the DNA from a particular individual contains a mutation in genes.
