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.
Here, sugar (a polar substance) is in solution with water (also polar). Mark where the hydrogen bonds will form. Hydrogen bonding occurs: Between atoms. Between molecules. Between cells Between any particles. Hydrogen bonding is: Strong and difficult to break, like polar covalent bonding. A strong attraction between charged ions, like ionic bonding. A weak attraction between polar molecules.
