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.
Linking just two of these sugars produces a disaccharide called cellobiose [ 2 ]. Cellulose is a polysaccharide produced by linking additional sugars in exactly the same way. The length of the chain varies greatly, from a few hundred sugar units in wood pulp to over 6000 for cotton.he links in the cellulose chain are a type of sugar: ss-Ã-d. Glucose two unlinked molecules of-Ss-Ã d glucose are pictured [ at ]. Right 1 the sugar units are linked when water is eliminated by-COMBINING the oh Group and h highlighted. in gray
