Steps dna profiling

網頁Visualizing the DNA fragments Once the fragments have been separated, we can examine the gel and see what sizes of bands are found on it. When a gel is stained with a DNA-binding dye and placed under UV light, the DNA fragments will glow, allowing us to see the DNA present at different locations along the length of the gel. 網頁2016年4月9日 · DNA Profiling Using STRs Educator Materials 4.
