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.
1 Disaccharides* â¢ Disaccharides: two monosaccharides can form a disaccharide through an acetal link. Sugars in the form of acetals are called glycosides, and the bond linking the anomeric carbon to the âOR group is often referred to as the glycosidic bond.
