DNA Sequences Activity DNA Sequences Draw the chain that carries some of the code for a organism, such as a person, trout chimpanzee or butterfly. Just like DNA there are four different kinds of units that make up the sequence – Red, green, yellow and blue. Your chain will contain two strands of colours that match up the same way the units (bases) in DNA do. That means if you know the sequence of one strand, you can work out the sequence of the other. Instructions (Written form) • We will be creating 3 different chains of DNA. ( 1 DNA chain for 3 different organisms). The following steps will be the same for all 3 chains. 1. Choose one DNA sequence to make 2. Set up your chain by lightly drawing two lines parallel to each other. 3. Look at the first letter in your sequence. Find the right colour (base)and draw into your chain. 4. With the 1st line having a colour (base) find the matching colour (base) and draw onto the 2nd line. 5. Repeat this colouring and drawing according to your sequence until you’ve finished the sequence Instructions (with visuals) 2)Set up your chain by lightly drawing two lines parallel to each other 3. look at the first letter in your sequence.
