These chromosomes exhibit a very characteristic banding pattern and are so big that they can be isolated even by freehand micro-manipulation. Thus, they represent an ideal tool for studying differential gene activation at the chromosome level.

Replication in Polytene Chromosomes,ed out on salivary glands of the higher Diptera. The view is taken that their chromosomes are synthesized by the same basic metabolic machinery that is used in other tissues and that phenomena observed in them should provide insights into the nature of the replication process in all cells.

Tho choose giant polytene chromosomes as the common denominator of a new volume may at first sight seem to set rather arbitrary restrictions upon a coherent discussion of the basic problem of cellular differentiation.
