Which one of the following statements about Pax6 and eye development is INCORRECT?
A)Binding of Pax6 protein to the cis-regulatory elements of its target genes results in activation of some genes and repression of others.
B)The specific program of eye development for a given species depends on the genes downstream of Pax6 in that species' genome.
C)In the fruit fly, the total number of genes downstream of Pax6 that are needed for eye development is approximately 2000.
D)Some of the genes influenced by Pax6 protein are activated or repressed indirectly by other transcription factors "turned on" by Pax6.
E)The downstream target genes for Pax6 protein in different organisms are all very similar.

Question

Quizplus · Accepted Answer

The incorrect statement is E because the downstream target genes for Pax6 protein can vary significantly between different organisms, reflecting the diversity in eye structures and developmental pathways across species. Pax6 plays a crucial role in eye development across species, but the specific target genes and pathways it influences can differ, contributing to the diversity of eye types in the animal kingdom.
