strands sep by helicase</p>

<p>

single stranded DNA binding proteins keep the strands from re-annealing;</p>

<p>

replicates from 5' to 3' end (using DNA polymerase III): &nbsp;no prob. for the leading strand but

how does lagging strand replicate? &nbsp;it forms in pieces called Okazaki frags.

first an RNA Primase lays down an RNA primer, then

DNA polymerase, &nbsp;then DNA Polymerase III lays down new DNA.

then &nbsp;DNA polymerase I replaces the RNA primers with DNA.

finally DNA ligase links together the Okazaki frags.</p>
