Step-by-step solution

Starch, glycogen and cellulose are homopolysaccharides as these consist of only one type of monomer. Starch and glycogen consists of branched and unbranched chains while cellulose has only unbranched chains. Hence when Iodine is added to starch and glycogen, it forms complexes with the branched part which appears blue or red respectively. These complexes are not seen in cellulose. DNA is made up of many nucleotides (monomers) which consist of phosphate, a pentose sugar and four types of nitrogen bases. Thus, DNA co
