DNA helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds down the center of the strand. It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA.
_____ Daughter strands are formed using complementary base pairing. _____ DNA unwinds _____ The DNA of the daughter strands winds with together with its parent strand. 2. Why is DNA replication called âsemi-conservativeâ? _____ 3. What enzyme unwinds or unzips the parent strand? _____ 4. What enzyme connects the new bases to the old bases in the DNA template? _____ 5. What enzyme connects the new nucleotides together and proofreads them? _____ 6. Show the complimentary base pairing that would occur in the replication of the short DNA molecule below. Use two different colored pencils (or different pens, markers, etc.) to show which
