Photoreactivation : Method of DNA Repair for the Recovery of UV Induced DNA Damages by Phytolyase Enzyme and Visible Light
Science is beautiful when it makes simple explanations of phenomena or connections between different observations. Stephen W. Hawking, 2011 What is Photoreactivation? Photoreactivation is a type of DNA repair mechanism present in prokaryotes, archaea and in many eukaryotes. It is the recovery of ultraviolet irradiated damages of DNA by visible […]

Molecular Biology MCQ-01: DNA repair is a cellular process that ensures the integrity and stability of the DNA molecule. The DNA in our cells can be damaged by various factors, including environmental agents such as radiation and chemicals, as well as internal cellular processes. If left unrepaired, DNA damage can […]
