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.
For example, glucose, galactose, fructose are some of the common molecules with six carbon atoms. For example, glucose has four hydroxyl groups and has the following structure. These are further divided based on whether they have an aldehyde group or a ketone group. Hexose is the group of monosaccharides with six carbon atoms whereas pentose is the group of monosaccharides with five carbon atoms. â¢Hexose molecules have more chiral centers than pentose molecules.
