WOS: 000252144300008Copper is essential to living organisms, but at elevated concentrations, copper may become toxic for living systems. During this research the effects of copper were evaluated at molecular levels in a marine green algae Ulva lactuca. In addition, the protection role of polyamines against DNA mutations and strand breaks against the copper treatment searched by RAPD-PCR analysis. The main changes observed in the RADP profiles have been resulted both in appearance or disappearance of different bands and variation of their intensity
