WebJun 14, 2024 · Figure 9.3. 1: During elongation, the bacterial RNA polymerase tracks along the DNA template, synthesizes mRNA in the 5’ to 3’ direction, and unwinds and rewinds the DNA as it is read. Termination Once a gene is transcribed, the bacterial polymerase must dissociate from the DNA template and liberate the newly made RNA. WebReverse transcription generates complementary DNA (cDNA) from RNA, and the cDNA can then serve as template in a variety of downstream applications for RNA studies. Therefore, it is important to recognize and prevent potential issues with cDNA synthesis to maintain the validity of experimental results. dynix horizon export services https://houseofshopllc.com
