Unknown quotes. There comes a time in life when you have to let go of all the pointless drama and the people who create it. 6 up, 2 down. favorite. Paul McCartney quotes. I think people who create and write, it actually does flow-just flows from into their head, into their hand, and they write it down.
A major type of UV light induced damage is the formation of cyclobutane pyrimidine dimers (PyrîîPyr) between adjacent pyrimidine bases in DNA exposed to UV radiation in the range of 200â300 nm (far-UV) [1] and [2] .
Cyclobutane dimers are the most common DNA lesions after exposure of cells to UV-B radiation. A quantitative method wasdeveloped to determine the frequency of thymine dimers in aquatic primary producers such as cyanobacteria, phytoplankton and ma croalgaeto study the effects of UV radiation. Genomic DNA was extracted and purified by using standard biochemical and molecular biologytechniques.
