BOTH QUESTIONS PLEASE.
Regulation of pattern formation during development depends upon altered gene expression. The majority of factors needed to generate these patterns regulate gene expression by: Promoting alternative splicing Changing phosphorylation of target proteins Altering mRNA stability Altering transcription of target genes Promoting protein degradation Question 4 3 pts Bicoid is important for generation of the anterior-posterior axis by regulating expression of multiple genes, including hunchback and caudal. How does Bicoid regulate expression of these two genes? Bicoid induces...
