DRAW a DNA molecules consisting of 6 nucleotides in length following the LABELING directions in steps 7 and 8. I recommend using circles for the phosphate groups, triangles for the sugar deoxyribose, rectangles for the purines Adenine and Guanine, and squares for the pyrimidines Thymine and Cytosine. 7. Draw the molecule of DNA you constructed using these symbols: D= deoxyribose, P=phosphate, A = adenine, G = guanine, C = cytosine, T = thymine. 8. Indicate the location of the hydrogen...
