1- Kruppel, a GAP gene, regulates expression of
bicoid
hunchback
eve
ftz

2- Not true about segmentation genes
genes from one tier can regulate expresion of genes from lower tiers
genes from one tier can regulate expresion of each other
are regulated via modular transcription elements
their regulation is independent from signal gradients

3- Gene regulatory modules regulate expression of segmentation genes by
sensing signal gradients
binding hunchback and bicoid
giant and Kruppel inhibition
binding egg-polarity genes

4- The regulatory information from egg-polarity genes results in
location of pair-rule gene expression
expression of GAP genes in particular locations
activation of gene regulatory modules
location of segment polarity gene expression

5- GAP genes provide information on ___ for regulation of the expression of segmentation genes
global positioning values
location of pair-rule gene expression
combined gradients of signals
location of segment polarity gene expression
