Abstract
It is argued that ultraviolet absorption by a DNA molecule (which gets biochemically attached to nearby photolyase enzyme so that the effect of uv absorption becomes macroscopically discernible) constitutes an intriguing example of quantum measurement. We point out that this does not merely illustrate the quantum measurement paradox in the hitherto unexplored arena of biological macromolecules, but is also instructive in highlighting specific difficulties inherent in various approaches to the measurement problem.Keywords
