Name ection: c) Shown below is the structure of a monomer used in nucleic acid sy N o2。-PBo-↓o-c, iWould this monomer be used to form part of an rna strand or a dna strand? Briefly explain your answer 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 7012Fall2003Name:___________________________________ Section:_____ 7.012 Fall 2003 c) Shown below is the structure of a monomer used in nucleic acid synthesis. γ β α OH H H O P O P O P O CH2 HO N N N N NH2 O O O H H O– O– O– O– i) Would this monomer be used to form part of an RNA strand or a DNA strand?
