SUMMARY
DNA absorbs ultraviolet light most effectively at a wavelength of 260nm due to the presence of aromatic bases, particularly adenine, thymine, cytosine, and guanine. This absorption peak is critical for quantifying DNA concentration in molecular biology applications. The 260nm measurement is commonly utilized in spectrophotometry to assess nucleic acid purity and concentration, making it a fundamental concept in laboratory practices.
