More than one answer is correct. Options: Polytene chromosomes and normal chromosomes contain the same amount of DNA, but the former are much larger because they contain large quantities histones. Polytene chromosomes are circular. Puffs on polytene chromosome puffs are sites of active protein synthesis. Polytene chromosomes are found in interphase. Puffs on polytene chromosome puffs are sites of active RNA synthesis.arrow_forward
