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.
The five carbon sugar(deoxyribose) attached to the phosphate group is joined to one another to form the sides of the DNA, forming a covalent bond of sugar-phosphate-sugar-phosphate etc. Also, one of 4 nitrogen bases of DNA are attached to the sugar, which is in turn attached to each other.The purines(double ringed base) which are A and G bond with the pyrimidines T and C respectively. The bonding between the two creates a hydrogen bond.he five carbon sugar(deoxyribose) attached to the phosphate group is joined to one another to form the sides of the DNA, forming a covalent bond of sugar-phosphate-sugar-phosphate etc. Also, one of 4 nitrogen bases of DNA are attached to the sugar, which is in turn attached to each other.
