WebDuring elongation, RNA polymerase "walks" along one strand of DNA, known as the template strand, in the 3' to 5' direction. For each nucleotide in the template, RNA polymerase adds a matching (complementary) RNA nucleotide to the 3' end of the RNA strand. [See the chemical reaction] WebSince GTP concentration in the cytoplasm is significantly lower than that of ATP, it is used for specific functions in cell metabolic processes. It's principle use is in protein synthesis when coupled with IF2 during ribosomal initiation, Ef-Tu and Ef-G during elongation and ; RF3 during termination.
