Step by step
Solved in 3 steps
- The early Drosophila embryo is a syncytium. Why is this significant? O a. it allows the segment polarity proteins, Wingless and Hedgehog, to function as morphogens to establish the segmental boundaries O b. it allows the establishment of transcription factor gradients, which provide positional information O c. it eliminates the need for localized cytoplasmic determinants O d. all of the aboveWhat factor does NOT contribute to establishment of the hunchback gradient in the Drosophila embryo? O a. maternal source of hunchback mRNA O b.nanos O c. bicoid O d. caudalHomeobox genes (a) are found in fruit flies but no other animals (b) tend to be expressed in the order that they appear on a chromosome (c) contain a characteristic DNA sequence (d) b and c (e) a, b, and c
- There is a gene in the fruit fly (Drosophila) called antennepedia. It controls the formation of which structures? What happens when it isIn mice, the copy of the Igf2 gene that is inherited from the mother isnever expressed in her offspring. This happens because the Igf2 genefrom the mothera. always undergoes a mutation that inactivates its function.b. is deleted during oogenesis.c. is deleted during embryonic development.d. is not transcribed in the somatic cells of the offspring.A Drosophila egg that is bed lbcd may develop normally, but the adult fruit fly will not be able to produce viable offspring. How is this possible? The mother can provide the bcd mRNA required for normal development, but the adult bcd /bcd female fly cannot make its own bcd mRNA. The Hox genes in the egg play a redundant role to bcd during development in a bcd / bcd egg, but reproduction requires bcd. Drosophila sperm contains the functional bcd gene product required for normal development, but the adult sex cells will not be able to produce the functional product. The nanos gene product functionally compensates for lack of bcd expression in the developing fly but not in its offspring.
- Draw a diagram to illustrate how a concentrationgradient of a transcription factor along the anterior–posterior axis of a Drosophila embryo can create a region in the middle inwhich transcription of a target gene takes place without beingtranscribed in either the anterior or posterior regionExplain what a morphogen is, and describe how it exerts its effects. What do you expect will happen when a morphogen is expressed in the wrong place in an embryo? List five examples of morphogens that function in Drosophila.A key event that initially determines female or male development in Drosophila is the a. transcription of the Sxl gene. b. alternative splicing of the Sxl pre-mRNA. c. expression of the ix gene. d. expression of the her gene.
- The figure below shows the distribution of proteins during embryo development in Drosophila. These proteins are encoded by which types of genes? Which proteins regulate the expression of these genes?Which of the following statement(s) is/are true with regard to positional information in Drosophila? A. Morphogens are a type of molecule that conveys positional information. B. Morphogenetic gradients are established only in the oocyte, prior to fertilization. C. Cell adhesion molecules also provide a way for a cell to obtain positional information.Genomic imprinting refers to the fact that A. some proteins are made from mRNA transcribed by the mother B. one cell type follows the developmental path of another C. the X-ray repair system is inactivated D. programmed cell death occurs E. gene activity depends upon whether the gene is of maternal or paternal origin
