34 - HIPFNER 5 Flashcards
what happens in drosophila development in the first 24 hours
what has already been defined by the 2 hour mark?
what was the first screen of the Heidelberg screen and what did it determine
what was the second screen of the Heidelberg screen and what did it determine
what is the timeline and the genes which act one after the other in Drosophila development
which two genes specify the AP axis
what is the gene product of bicoid
encodes a transcription factor
offspring of bicoid mutant mothers lack anterior segments
what is the anterior Bicoid protein gradient
what happens when you transfer bicoid from one egg to the other (WT to mutant)
how do nanos and maternal hunchback work
what are gap genes and what do they do
what characterizes gap gene mutants
how are gap genes regulated
transcriptionally regulated by maternal effect gene products
zygotic hunchback has 3 binding sites for Bcd in the hb promoter
what characterizes pair rule gene mutants
characteristics of pair rule genes
how is pair rule gene expression regulated
regulated by maternal effect and gap gene
even-skipped (eve) nuclei in each stripe have specific concentrations of maternally loaded and zygotic factors
how do stripe specific even enhancers work
characteristics of segment polarity genes
what are homeotic mutations and some examples
characteristics of hox genes
