Localized squamous cell carcinoma (SCC) of the skin is a highly curable disease.[1] There are a variety of treatment approaches to localized SCC, including excision, radiation therapy, cryosurgery, and electrodesiccation and curettage.
In bacteria, transcription begins with the binding of RNA polymerase to the promoter in DNA. RNA polymerase is a core enzyme consisting of five subunits: 2 Î± subunits, 1 Î² subunit, 1 Î²' subunit, and 1 Ï subunit.he antisense strand of DNA is read by RNA polymerase from the 3' end to the 5' end during transcription (3' â 5'). The complementary RNA is created in the opposite direction, in the 5' â 3' direction, matching the sequence of the sense strand with the exception of switching uracil for thymine.
After transcription, the new RNA strand is released and the two unzipped DNA strands bind together again to form the double helix. Because the DNA template remains unchanged after transcription, it is possible to transcribe another identical molecule of RNA immediately after the first one is complete.
