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 fructose & glucose monomers in a sucrose polymer are held together using a glycosidic bond. A type of covalent bond that joins a carbohydrate (sugar) molecule to another group, which can be another carbohydrate (or not).
