WebMicroarrays Made Simple: “DNA Chips” Paper Activity A DNA microarray (DNA chip) is an ordered array of different known sequences of DNA (~20-70 bases long). These DNA sequences represent many of the genes in an organism. Many copies of each different sequence are stuck to one “spot” on a solid surface (glass). A DNA chip can. . WebDNA microarray analysis is a technique that scientists use to determine whether genes are on or off. Scientists know a gene is on in a cell if its mRNA is present. What is a DNA Microarray?

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). green building declaration formWebIn the tissue microarray technique, a hollow needle is used to remove tissue cores as small as 0.6 mm in diameter from regions of interest in paraffin-embedded tissues such as clinical biopsies or tumor samples.
