Hi, I'm Joy Waldinger, and I'm a practicing artist and an art education major. Today I'm gonna be teaching you how to make a child's DNA strand model. As a future educator I want to use art to help people learn things. So today we're gonna learn more about the DNA strand as we make it. The materials for this project include a paper towel roll, a ruler, a couple pieces of pastels or markers, string, glue, tough cardboard paper and scissors. So first things first, we're gonna take our tough cardboard paper and we're gonna draw out a large box that has a width of 10 centimeters and a height of 20 centimeters. We're gonna mark the center at 5 centimeters and we're gonna draw a line. Next thing we're gonna do is we're gonna go from the left and right edges and mark off 1 centimeter and draw a line for the tabs. The tabs are gonna be used to glue to the backbone of our model. Next we're gonna chunk out 2 centimeters for the width of each base pair and go all the way down and draw lines across horizontally. So we're gonna be creating 10 base pairs that go all the way down our box. So A always pairs with T, so adenine always pairs with thiamine and C always pairs with G, cytosine and guanine. So we're gonna be writing these letters down alternating on our piece of paper. We're gonna give each base pair a color. So adenine is gonna be green, thiamine is gonna be pink, cytosine is gonna be orange and guanine is gonna be blue. So, we're gonna cut them out and then place them to the side after folding the one on the left front and the one on the right back. Once you have your base pairs folded and to the side, we're gonna work on the sugar phosphate backbone of our model. So we're gonna take our paper towel roll and we're gonna trace with a Sharpie the line that is already there that already has a spiral. Then we're gonna take our scissors and we're gonna cut that line. Then we're gonna cut that also in half and use the two small pieces for the backbone of our DNA model. Next, we will be taking our two strips and using a ruler to mark every 2 centimeter where we'll write S and P alternating. S standing for sugar and P standing for phosphate. Next we'll be coloring those in, we'll be coloring the sugars red and the phosphates yellows, alternating down the line. We will do this to both sides. Then we will add our base pairs to the center. Now, what you'll want to make sure of is that the paper towel roll does not lose its spiral because that is essential to creating the double helix. So, we're gonna be using glue on the tabs that we've created on our base pairs and then placing them down our paper towel roll. So there you have it, your very own DNA strand that you can review before your science test. Thank you for watching, have a great day.
