What is the backbone of DNA?
Each nucleotide contains a phosphate group, a sugar, and a nitrogenous base. The phosphate groups serve as the "backbone" of DNA while complementary base-pairing between nucleotides (adenine pairs with thymine, guanine pairs with cytosine) form the inside of the molecule. Thanks!
What pairs with cytosine?
After you’ve assigned the colors, you can accurately pair the complementary bases. Adenine always pairs with thymine, while guanine pairs with cytosine. So, if you have a red (adenine) pipe cleaner on one side, put a blue (thymine) pipe cleaner in the same spot on the other side, and so on.

Then, carefully holding the DNA model, twist it at least once around until it looks like a double spiral. Tape the other end to a flat surface.
What are the steps of DNA ladder?
The "steps" of the DNA ladder are pairs of bases: adenine (A) and thymine (T) or cytosine (C) and guanine (G). The order of the base pairs holds the specials code for how living things grow and develop.
How to make DNA look like a ladder?
Be sure to leave some room at the ends of the strips. Make sure all the toothpicks are pushed halfway through the holes. Gently spread the two strips apart until your model looks like a ladder. This is what DNA would look like if it weren't twisted.
What is the shape of DNA?
They used Tinkertoy-like models to show that DNA is shaped like a twisted ladder. This shape is called a double helix. Watson and Crick also figured out that DNA is made of chemicals called bases .
