WebMechanisms of DNA Repair: There are four major pathways through which thymine-thymine dimer in DNA is repaired: light induced repair (photo-reactivation) and light-independent … WebFigure 1. Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration. Stage 1: Fixation

WebApr 24, 2024 · Spongy bone is also called cancellous or trabecular bone. It is found in the long bones and it is surrounded by compact bone. The term spongy comes from the fact that it is a highly vascularized and porous tissue. Trabeculae are spaces created in the tissue by thin areas of osteoblast cells. WebThe UV damages caused in cells are repaired after exposure of cells in visible light. This is called photo-reactivation. In this mechanism an enzyme DNA photolyase cleaves T-T dimer and reverse to monomeric stage (Fig. 9.17). This enzyme is activated only when exposed to visible light. The mutant cells lack photolyase.
