Challenge 3: Polymerize DNA

EXPLORE THE BIOLOGY:

DNA is a polymer.  Polymers (poly = many) are large molecules made of smaller, linked units called monomers (mono = one). 

DNA is made up of many, individual nucleotides (monomers) that are connected to each other to form both single strands and helical, double strands (polymers).  Nucleotides are attached to a growing strand by an enzyme.    

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 3:  What enzyme will attach nucleotides to form double stranded DNA?

Hint:  You will need to move an enzyme and nucleotides into one place together to form new DNA.

Question 4:  What do you notice about the shapes of the nucleotides?
