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.
Structural. 1  Î² Glucose chains, like the one above, are called Cellulose molecules, and can contain 10000 glucose units. 2  Cellulose fibres are arranged in a very specific way and can be described as being like a fractal. 3  Macrofibrils have a very high mechanical strength, similar to that of steel. 4  Microfibrils can have special roles. 5  Other ...
