Differentiation of organs and tissues in a developing organism, is associated with:

Step-by-step solution

Differential expression of different genes at different stages of development leads to organ and tissues differentiation, for example, size and pattern of puffs of polytene chromosomes, which are site of transcription, varies at different developmental stages, indicating differential gene activity. Transcription factor is the molecular basis of organ differentiation. Related Theory The fate of a cell describes what it will become in the course of normal development.
