How are the gradients of maternal and zygotic proteins
established during early embryogenesis in Drosophila? Explain how
these genes control the expression of GAP genes along the AP axis
of Drosophila.
A) How are the gradients of maternal and zygotic
proteins established during early embryogenesis in Drosophila?
B) Explain how these genes control the expression of
GAP genes along the AP axis of Drosophila.
Explain how the primary transcript of a single eukaryotic gene
can produce different proteins, using Drosophila
sex-specific courting behavior as an example.
Briefly describe how genomic imprinting can be inferred from
inheritance patterns in human pedigrees.
1. Explain how one gene in Drosophila can code for 17,500
different nerve cell surface proteins.
2. Outline two modification of the structure of the nucleosome
that regulate transcription.
3. Outline how the structure of the operon (location of the
promoter, the sequence of genes and the locations of stop and start
codons in the mRNAs) allow for coordinated control of an enzymatic
pathway.
4. Compare and contrast a repressible operon to an inducible
operon. Give one example of each.
Explain the adjustments in maternal metabolism during pregnancy
for the following macronutrients: carbohydrate, protein, and
fat.
HOW and WHY do these changes
occur and what effect do they have on the mother and the fetus?
Explain the land rent gradients for four activities:
manufacturing, agriculture, offices and housing and how – in a
simple city model – land is allocated to one or the other use.
