Studies from the sea urchin developmental biology, Eric Davidson’s group envisions a network involving cis regulatory elements (such as promoters and enhancers) in a logic circuit connected to one another by transcription factors. Following statements are given regarding to this network.
A. The network receives its first inputs from transcription factors in the egg cytoplasm.
B. The network self-assembles from the ability of the maternal transcription factors to recognize cis-regulatory elements of particular genes that encode other transcription factors.
C. The new set of transcription factors activate autocrine signaling pathways that activate specific transcription factors in neighboring cells.
D. This network of interconnections among genes that specify cell types known as a gene regulatory network (GRN).
Which of the following statements are correct?
