Hydrogen bonds<span> are much weaker than covalent bond because of its bond is formed through fundamentally electrostatic interactions.
Hydrogen bonds happen due to dipole-dipole attraction while covalent bonds happen when valence electrons are shared.
Reasons why complementary nucleotides across the double-stranded dna bond together using hydrogen bonds rather than covalent bonds are (1) the distance between two strands, (2) size of the bases, (3) geometry of each base.</span>

When a test is conducted and it shows the presence of a red or red-violet color in the surface alcohol layer it means the result is positive
But when the colour is yellow it indicate negative reaction due to glucose fermentation.
A deviation from two color may also occur when we have an orange color. This colour change is due to the presence of methyl indole
When there is no color change this indicate No decarboxylase which is an enzyme needed for the fermentation reaction.
Color changes are indicator of how successful the reaction was.
