WebQuestion 1: Complete the following sentences on E coli DNA polymerase (1 mark each, 10 total) • In the DNA polymerase active site, a 3’ –O- nucleophile attacks a phosphate in the incoming dNTP to elongate the growing strand. Here, the reaction intermediate is stabilized by this metal ion: Mg2+ (for the most part), Zn2+ • The metal ion described in (a) is … WebSep 19, 2014 · The Role of KCl and MgCl2 in PCR. The Role of KCl: The KCl salt in the PCR buffer acts by neutralizing the charge present on the backbone of DNA. During the elongation step of the PCR, the primer has to anneal or stick properly to the template and this is facilitated by the KCl. Thus, it functions by reducing the repulsion between the ...
