Which of the following applies to the female sex determination in Drosophila melanogaster fruit flies? (Mark all that apply) When the X:A ratio is 1.0, the SXL gene is transcribed during the early embryonic stages. The SXL protein inhibits the expression of female differentiaion genes The SXL protein promotes the correct splicing of the Tra pre-mRNA so that functional Tra protein is made. The presence of the SXL protein promotes the correct splicing of the SXL pre-mRNA during later embryonic stages to ensure to continuous production of SXL protein. The Tra protein will stimulate the expression of male-specific genes.

Progesterone is a steroid hormone (also described as a ligand) that prepares the body for pregnancy. It binds to the progesterone receptor (PR) protein in the cytoplasm of various cells. Ligand bound PR acts as a transcriptional activator, binds to the DNA in the promoter region of several genes and leads to transcriptional activation of these genes. Which of the following statements must be true for the PR protein? O Ligand binding to the PR results in a conformational change in the primary structure of the protein The domain/region of the PR protein that interacts with the DNA, has basic amino acids Ligand binding to the PR results in a conformational change in the tertiary structure of the protein The domain/region of the PR protein that interacts with the DNA, has acidic amino acids
Which of the following statements about sex determination in Drosophila is false? Males transcribe sex-lethal, females do not. The X/A ratio controls the transcription of sex-lethal. Double-sex RNA is spliced differently in males and females. Transformer regulates the splicing of double-sex RNA. Functional transformer protein is only produced in females.
Explain the Drosophila genetics tool for gene expression known as the UAS-GAL4 system
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.

I. The retinoic acid receptor (RAR) is a transcription factor that is similar to steroid hormone receptors. Thesubstance (ligand) that binds to this receptor is retinoicacid. One of the genes whose transcription is activatedby retinoic acid binding to the receptor is myoD. Thediagram that follows shows a schematic view of theRAR proteins produced by genes into which one oftwo different 12-base double-stranded oligonucleotides had been inserted in the ORF. The insertion site(a–m) associated with each mutant protein is indicatedwith the appropriate letter on the polypeptide map.For constructs encoding proteins a–e, oligonucleotide 1(5′ TTAATTAATTAA 3′ read off either strand) wasinserted into the RAR gene. For constructs encoding proteins f–m, oligonucleotide 2 (5′ CCGGCCGGCCGG 3′)was inserted into the gene.NH2 f g h i j k l m COOHa b c d eThe wild-type RAR protein can both bind DNA and activate transcription weakly in the absence of retinoic acid(RA) and strongly in RA’s presence.
