Transcription of two genes. (a) RNA polymerase moves from the 3â² end of the template strand, creating an RNA strand that grows in a 5â² â 3â² direction (because it must be antiparallel to the template strand).
The atoms in sugar do not form ions; instead, they share their electrons. The type of bond that forms from the sharing of electrons between the atoms of the table sugar is a covalent bond. Table sugar has a much more complex chemical structure than salt.
The chemical bond linking them is an N- glycosidic bond. (3) Phosphate Group(s) Mono-, di-, and triphosphates. Phosphate can be bonded to either C3' or C5' atoms of sugar. A nucleotide is a 5'-phosphate ester of a nucleoside.
