If one strand of DNA has the sequence 5’-ATTCGAGC-3’, what is the complementary strand? Be sure to label the 5’ and 3’ ends.

| Enzyme | Function | |--------|----------| | | Unwinds and separates the double helix by breaking hydrogen bonds. | | DNA Polymerase III | Synthesizes new DNA strands by adding nucleotides to the 3’ end; also has 3’→5’ proofreading ability. | | Primase | Synthesizes a short RNA primer to provide a 3’-OH group for DNA polymerase to begin adding nucleotides. | | Ligase | Seals nicks (joins Okazaki fragments) on the lagging strand by forming phosphodiester bonds. | | Topoisomerase | Relieves supercoiling ahead of the replication fork to prevent DNA breakage. |
