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.
Glycosidic Linkage. There are mainly two type of carbohydrates. Simple carbohydrates-are also called as sugar and exist in either a natural or refined form. Natural sugars are found in fruits and vegetables. disaccharide can be composed of two same sugar molecules like maltose, which is composed of two D-glucose molecules linked through a glycosidic bond, or two different hexose sugars like lactose formed with D-glucose and D-galactose.
