Final answer:
Transcription factors control the formation of body axes, segmentation, development of segment characteristics, and cell differentiation during pattern formation in the human embryo.
Step-by-step explanation:
Transcription factors control the formation of body axes, segmentation, development of segment characteristics, and cell differentiation during pattern formation in the human embryo.
During development, specific sets of genes are expressed in embryonic stem cells, which determine their ultimate cell type. The process of differentiation is regulated by location-specific chemical signals from the embryonic environment that set in motion a cascade of events controlling gene expression.
