how to make a paper dna model

Best answer


Step 1:Mark It Down the Middle Mark the paper down the middle. On a standard sheet of paper that’s 4 1/4. Step 2: Marking Out the Sugar- Phosphate Backbone. Make one line 3/8 from each edge and do the same on either side of the middle line. This creates the Sugar Phosphate Backbone of the DNA.

  • How do you make a 3-D model of DNA?

  • Follow these steps to make your very own 3-D model of DNA. Remember, DNA is shaped like a double helix or twisted ladder. First, make the sides of the ladder. To do this, cut two strips of colored paper that are at least two feet long and about one inch wide. (If your paper’s not long enough, tape a couple of strips together.)

  • How do you make a DNA model with green and white?

  • Take 24 of the balls and paint 12 green and leave 12 white. These green and white balls will make up the strands that run along the outside of your DNA model, or the sugar and phosphate of your double helix. To paint half of the balls green, use a paintbrush to apply a thin layer of green, water-based paint.

  • What does a DNA model look like?

  • (The phosphorus bonds are the white circles and lines) The DNA model should look like a ladder with one leg lower/higher than the other. Try twisting it to see if you could get it to look like a double helix. Terms/Concepts:Double Helix; Adenine; Thymine; Cytosine; Guanine; Genes; Chromosomes; Mutations

Use a pencil and a ruler to mark each inch along one strip.
