Preview - Exploring Dna Replication

Challenge 2: Unzip the DNA

EXPLORE THE BIOLOGY:

DNA (DeoxyriboNucleic Acid) is made of two strands which wind around each other in a double helix.  When DNA is replicated, the DNA strands are separated and each serves as a template (i.e. the basis for a pattern) for a new double helix.

DNA-strand-length:  30                                            Speed:  Normal

Enzyme labels: checked                                          Substitutions:  unchecked

Nucleo labels: unchecked                                       Free-nucleosides:  50                   Time-limit:  None

Questions

Please answer the questions below.

Question 2:  Which enzyme unzips the double stranded DNA? (Use the model to answer)
