(C) Balbiani discovered giant chromosomes in the salivary glands of $Chironomus$ larvae,which are known as polytene chromosomes.These chromosomes are characterized by a series of dark and light transverse bands.They also exhibit large,puffed-out regions known as Balbiani rings or puffs,which are essentially loops of chromatin representing sites of active transcription.Therefore,these chromosomes are recognized by the presence of both bands and loops.
