How does a polytene chromosome differ from a typical eukaryotic chromosome?
What will be an ideal response?
Polytene chromosomes are found in a variety of tissues in the larvae of some flies and several species of protozoans and plants. A polytene chromosome contains banding patterns and is large because of repeated replications of DNA without nuclear division, which is not the case in typical non-polytenic chromosomes.
