draw a reaction showing the formation of a phosphodiester bond joining two nucleotides (one containing thymine and one containing guanine) in DNA. Do not paste in a copy of a figure. Be sure to start with the 5' end on the left side & to show which nucleotide loses -OH and which loses -H groups to form a molecule of water. Remember to draw the bases associated with the nucleotides and also label them as either a pyrimidine or purine.
