Popis:	A culture of HeLa cells was subjected to concurrent and consecutive dichromatic irradiation with visible light of various wavelengths. Consecutive dichromatic irradiation in the sequence 760 nm+633 nm was found to stimulate the synthesis of DNA in the cells and that in the sequence 633 nm+760 nm to inhibit it. These effects reached their maxima when the time interval between the successive irradiation events came to (1⋎3) min. On the strength of these data it is supposed that in HeLa cells there may exist a photochromic, photoreversible pigment similar to photochrome. Based on the results of dichromatic irradiation with blue and red light, flavoproteins are being discussed as likely photoreceptors.
