Dna encodes the genetic blueprint of a life form using four chemicals. it is a long molecule that looks a little like a rope ladder, only about 200,000,000 times smaller! give the long "ladder" a clockwise twist, and you can see why dna is also called the "double helix." following the instructions below, you will make a candy model of a piece. Instructions for making a candy dna model. remember c and g and t and a always pair up, so assign a colour to each nucleotide and add pairs of sweets to your cocktail sticks. attach each end of the cocktail sticks to your liquorice, spacing them evenly apart. once you have a long enough string, twist it to give the spiral shape of a double helix.
Step 1. make your base pairs. start your candy dna model by sorting the 4 colors of candy into separate bowls. then you want to assign each one to a specific nucleotide. these 4 nucleotides along with the sugars and phosphates make up your double helix candy dna model. adenine. A double helix dna molecule is a twisted ladder like structure that consists of base pairs attached to the sugar phosphate backbone. the dna molecule was discovered by watson and crick. one strand of double helix dna is complementary to the other strand. each strand starts with 5’ and ends with 3’. 2. prepare your other supplies. gather string and toothpicks to be used in creating the model. the string should be cut to be about 1 foot (30 cm) long, although you can make it longer or shorter based on your preferred size of dna model. [11] use 2 pieces of string that are the same length to make the double helix. Specification: item type: diy human dna model material: pvc use: can be used for children scientific diy or education teaching toy package list: 1 x base 1 x top cover 1 x bottom column 15 x structural column 2 x structural plates 2 x pull strips note: this product contains small parts, kids should be used under the supervision of adults to avoid accidental ingestion by children.
