i. Draw the chemical structure of the following double-stranded DNA molecule. Then, identify and label the bonds that exist in the DNA molecule you have drawn. 5' ATTG | | | | TAAC 5' ii. What is the net charge of the DNA molecule? Which part of the DNA molecule contributes to the property? iii. The human genome is distributed in 23 pairs of chromosomes with approximately 3 billion base-pair. How does a human cell pack such a massive number of DNA inside its nucleus?

Draw the complete structure of a DNA molecule in which one "trinucleotide" strand has the following sequence 5'-TAG-3'. Show both strands of the DNA molecule. Draw all of the atoms present in the molecules and be sure to label the ends of each strand. Identify the bases by their one letter designation and use hatched or dotted lines to indicate the position of hydrogen bonds.
