- 1) Are NGN2-induced neurons (NGN2-iNs) the same as the cells in neural organoids? If not, how are they different? 2) Forced expression of the transcription factor neurogenin 2 (NGN2) induces human neurons, but to mature into electrophysiologically active neurons the require the presence of another cell type: what is that? 3)What kind of expression of NGN2 is associated with a central nervous system (CNS)-like cell? How do you know this?Following a mutagenesis experiment to identify novel genes affecting the circadian clock in Drosophila melanogaster you discover several mutants. You start considering two of those mutants that you call c and d. The two homozygous c/c and d/d are arrhythmic (arrhythmic is the definition of their phenotype), whereas the two heterozygous C/c and D/d are rhythmic (rhythmic is the definition of their phenotype) with a 24h period. You make two true-breeding stocks: stock 3 homozygous for c and stock 4 homozygous for d. You cross them in both directions and in both cases you observe complementation with no difference between males and females. Then you take the progeny of one cross, for instance the F1 of Females 3 x Males 4, and you perform a Testcross. Out of 1000 flies resulting from the lestcross only 125 are rhythmic. Using the number of flies expected for the Parental and the Recombinant genotypes and the formula that defines recombination frequency, what is the distance between loci C…Following a mutagenesis experiment to identify novel genes affecting the circadian clock in Drosophila melanogaster you discover several mutants.

- Which of the following is NOT true about the specification of the eye field? (Check all that apply) A ET induces RX, which in turn induces Otx2 and Pax6. B During late gastrulation, the forebrain and hindbrain are specified. Pax6 initiates the expression of a network of transcription factors, some of which mutually activate one another. D ET induces RX, which in turn induces Pax6 and blocks Otx2 within the eye field. ET induces RX, which in turn blocks Otx2 and Pax6. F During early gastrulation, Noggin promotes the expression of both ET and Otx2. During late gastrulation, Otx2 blocks the inhibition of ET by Noggin. H) It starts with neural induction when the neural plate is induced within the ectoderm. Pax6 is only required for the specification of the retina. During early gastrulation, Noggin indices Otx2 but blocks ET. E Feedback That's not correctBased on the NCBI Blastp and reciprocal analysis, are there any mutations to suggest that mus musculus is a good model to test the human FGFR3 gene. This is the only model we have to go off of to predict whether a mouse is suitable. I can’t seem to grasp what exactly I’m suppose to look for in these two photos.Please asap
