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.
Sugars can be anything from a single sugar molecule up to several bound together. When organic molecules are bound together, a bonding site must be freed up on each participant. This happens by clipping a single hydrogen from one participant, and an oxygen-hydrogen piece (hydroxide) off of the other. Where each bit used to be become the new bond, and the two freed pieces stick together as H2O.
