Structure of RNA Molecule.
Label the phosphate-sugar/phosphate-ribose backbone using a bracket, 5’ end of the strand, 3’
3nd of the strand, nitrogenous bases using a bracket, ribose sugar molecule in 1 nucleotide, a
phosphodiester covalent bond, C atoms 1’ to 5’ in one sugar molecule only. Circle one
nucleotide molecule as well.

Structure of DNA Molecule.
Label the phosphate-sugar/phosphate-deoxyribose backbone using a bracket, 5’ to 3’ strand, 3’
to 5’ end strand, nitrogenous bases using a bracket, deoxyribose sugar molecule in 1
nucleotide, a phosphodiester covalent bond, C atoms 1’ to 5’ in one sugar molecule only. Circle
one nucleotide molecule. Label the hydrogen bonds between a pair of bases, add the missing
hydrogen bonds between bases, complete the base sequence of the opposite strand.
