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.
Sugar is a highly polar molecule, with potential to form hydrogen bonds everywhere, and it feels much more at home in the highly polar solvent water (which also has lots of possibilities for strong hydrogen bonding networks) than in the moderately polar solvent ethanol (which has less hydrogen bonding power).ugar is a highly polar molecule, with potential to form hydrogen bonds everywhere, and it feels much more at home in the highly polar solvent water (which also has lots of possibilities for strong hydrogen bonding networks) than in the moderately polar solvent ethanol (which has less hydrogen bonding power).
