Question
Your task is to build a spiral staircase that is modeled after a DNA molecule. The staircase must have 12 steps, and each step needs to be 6 feet wide with two rails along the sides. Below, you have the possible materials to build this staircase Components of the steps: Making the rails: Sugar Adenine Guanine Cytosine Thymine Uracil Size of the components of each step can be: OR 2 feet Nails connecting each component can be: 4 feet Instructions: 1- Part One: Identify whether you'll be using material A or B to make the rails, explain why bak ova you chose one and not the other. The phosphate group has a role in this staircase/ DNA molecule, please indicate whether this functional group is a part of the steps or the railing. Identify the one step component that will not be used to create this staircase, and explain why we do not need this component for this project.

Be sure to include all of your group members' names in the comments section so everyone can get credit. Finally, hand it to someone in the teaching team.Explanation / Answer
1) The material B will be used to make rails because it contains the deoxy form of sugar. The phosphate group forms one of the important components of rails by alternating with sugars. The staircases will be formed by nitrogenous bases. In this structure, uracil will not be used as uracil is present only in RNA strands.
2) In double stranded DNA, adenine binds with thymine through two hydrogen bonds and guanine binds with cytosine through three hydrogen bonds. This is known as base pairing rule or chargaff's rule.
