In CAM plants, formation of the C4 acids is both temporally and spatially separated. At night, CO2 is captured by PEP carboxylase in the cytosol, and the malate that forms from the oxaloacetate product is stored in the vacuole

#Unit 3. Fundamental Processes

Thymine dimers cause mutations in two ways. (1) Dimers perturb the structure of DNA double helices and interfere with accurate DNA replication. (2) Errors occur during the cellular processes that repair defects in DNA, such as UV-induced thymine dimers To identify chemicals that are converted into mutagens in the liver, the Ames test treats potential indirect mutagens with a mixture of liver extract
