      Steps of DNA replication. 1. DNA helicase (enzyme) unwinds the DNA. The junction between the unwound part and the open part is called a replication fork. 2. DNA polymerase. adds the complementary nucleotides and binds the sugars and phosphates. DNA polymerase travels from the 3' to the 5' end. The DNA is called the

      4. Nucleotides can only be added to the 3' OH end of the chain so growth goes from 5' to 3' direction -- region of unwinding DNA is called replication fork -- individual nucleotides coming in have 3 phosphate groups attached, but two are lost, supplying energy and the last remains with the nucleotide on the strand. 5.

      Using your notes, book, and this assignment, place the steps of DNA replication in the correct order. ____ a. The enzyme DNA polymerase moves along the exposed strands and adds. complementary nucleotides to each nucleotide in each existing strand. ____ b. The DNA double helix breaks or unzips down the middle between the base pairs.

      You will draw out the steps of DNA replication. In each box, draw the event described. You will use 3 different colors: one for the original strands of DNA, one for the leading strand, and one for the lagging strand. You must label all the bold words in each drawing. 1. Draw the DNA double helix, with the sequence on the 5’ to 3’ strand:

      DNA replication begins at specific regions of DNA referred to as 'Origins of Replication' or ori sites. ... All DNA is synthesized in the 5' to 3' direction. Steps. DNA is unwound. RNA primer is made at fork. DNA polymerase adds nucleotides to 3’ end. DNA polymerase runs into previous primer.
