Non-template activities of DNA/RNA polymerases and their significance
Pokorná, Kristýna ; Vopálenský, Václav (advisor) ; Pospíšil, Jiří (referee)
Non-templated addition of adenosine on the 3' end of the product of several DNA polymerases commonly used in molecular biology has been a problematic yet unexplained phenomenon for a few decades now. The only other instance where adenosine is added to the 3' end of an information molecule in a cell is polyadenylation. At the same time, several RNA viruses appear to perform similar action to either edit or polyadenylate their mRNAs. This work focuses on the details of these three highlighted processes and relationship between them and has found out that all of them appear to stem from a common conserved property of the ancestral polymerase. Key words: DNA polymerase, RNA polymerase, non-templated addition, Taq polymerase, polyadenylation
