During Drosophila development, there is a regulatory cascade of gene activation. The proper sequence for this cascade is ________.
A) bicoid, gap genes, pair-rule genes, and segment-polarity genes
B) bicoid, pair-rule genes, gap genes, and segment-polarity genes
C) bicoid, segment-polarity genes, gap genes, and pair-rule genes
D) bicoid, gap genes, segment-polarity genes, and pair-rule genes

Question

Quizplus · Accepted Answer

The correct sequence for gene activation during Drosophila development starts with the maternal effect gene bicoid, followed by the activation of gap genes, then pair-rule genes, and finally segment-polarity genes. This sequence is crucial for the proper segmentation and development of the embryo.
