WebWhat enzyme removes RNA nucleotides from primer? DNA polymerase The enzyme ribonuclease H (RNase H), instead of a DNA polymerase as in bacteria, removes the RNA primer, which is then replaced with DNA nucleotides. How are RNA primers synthesized? In living organisms, primers are short strands of RNA. WebDNA polymerase Ⅰ removes the RNA primer from lagging strand by 5’→3’ exonuclease activity and also fills the gap. DNA Polymerase II is coded by polB gene. It is made up of 7 subunits. ... Whereas DNA polymerase 1 is the main enzyme for repair, removal of primers and filling the gaps in the lagging strand. Apart from polymerisation and 3 ...
