The strand are not anti-parallel In dNa there should no be any ur's G would not base-pair with T ii)What type of chemical interaction is indicated by a"I"in the above diagram? What happens to these interactions during DNA replication? This line indicates hydrogen bonding between the two complementary bases. It would represen 2 hydrogen bonds between A and T or 3 hydrogen bonds between G and C. these bonds are disrupted to allow replication of the dNa and new bonds form with the newly synthesized strands c) Shown below is the structure of a monomer used in nucleic acid synthesis NH. HO i Would this monomer be used to form part of an rna strand or a dna strand? Briefly explain your answer RNa because it has a 2'Oh ii)In nucleic acid synthesis, one of the phosphate groups of this monomer is covalently linked to a new strand that is being elongated. In the figure above, draw a circle around the phosphate group that would be linked iii)When this monomer is already part of the newly synthesized strand, one of the hydroxyl groups of this monomer will be linked to the phosphate group of the next monomer added. In the figure above, draw a box around the hydroxyl group that will be linked 012Fal20037.012 Fall 2003 • The strand are not anti-parallel • In DNA there should no be any U’s • G would not base-pair with T ii) What type of chemical interaction is indicated by a "|" in the above diagram? What happens to these interactions during DNA replication? This line indicates hydrogen bonding between the two complementary bases. It would represent 2 hydrogen bonds between A and T or 3 hydrogen bonds between G and C. these bonds are disrupted to allow replication of the DNA and new bonds form with the newly synthesized strands. c) Shown below is the structure of a monomer used in nucleic acid synthesis.
