PROCEDURES<br>1. Cut out 30 pieces of the model and fold them as described in figure below.<br>2. Cut the straws to make 30 of 1.5-cm pieces.<br>3. String together the cut-out nucleotides and 1.5-cm straws. Every 2 nucleotides should have<br>a straw in between.<br>4. Glue the folded parts of the nucleotides together. Arm # 1 of a nucleotide should be glued<br>to the arm # 2 of the one above it, and the arm # 3 of the below glued to the arm # 4 of the<br>above. This will make a helical strand of 30 nucleotides.
