In Mr.Robinson’s science 9 class, our assignment was to make a DNA strand using liquorice, mini coloured marshmallows and tooth picks. DNA is found in the nucleus of a cell and it create your characteristics. DNA stands for deoxyribonucleic acid. The DNA you have are copy’s of your parents passed down to you.
There are four different types of nitrogen bases, (A) adenine, (T) thymine, (G) guanine and (C) cytosine. Their is always a pattern for the four chemical bases. The pattern we used in class was TAC GTA TGA AAC. As you can see in the photos their are two strands of DNA, the DNA strands act as a blue print for the other DNA strand. -Angie Johnston
