Replication in Bacteria circular Helicase Separates DNA Brainpower Read More Primase makes RNA primer at the 5' end of the leading strand or the 5' end of each Okazaki fragment Single-Stranded binding protein holds DNA strands apart for replication Topoisomerase relieves overwinding by cutting and reattaching surrounds helices on either side of the expanding replication bubble DNA Polymerase III creates new DNA strand by adding nucleotides to the te...

DNA Replication Written Exam . DNA replication steps 1) Helicase- unwinds the parental double helix 2) DNA topoisomerase - upstream of helices alleviating torsional strain 3) Single-strand binding proteins (SSBP) stabilize unwound DNA, aided by DNA gyrase (topoisomerase). 4) Primase synthesizes a short RNA primer for DNA polymerase to bind to in the 5' to 3' direction to start replication on each strand. 5) DNA polymerase synthesizes the leading strand in 5' to 3' direction...
