Tumors that arise from exposure to mutagens, such as melanomas (UV light) and lung carcinomas (tobacco smoke) the number of mutations may be hundredfold greater than this. These altered proteins are known as neo-antigens

In addition to the fluence, some phytochrome responses are sensitive to the irradiance, 2 or fluence rate, of light. The units of irradiance in terms of photons are moles of quanta per square meter per second (mol m–2 s–1).

The ter site is recognized by a unidirectional contrahelicase (called Tus in E. coli and RTP in B. subtilis) that recognizes the consensus sequence and prevents the replication fork from proceeding.
