- Shown in this diagram, describe (and connect) 5 outcomes that could occur due to loss of FMRP function in this cell. Explain your thoughts with sentences.Shown in this diagram, describe (and connect) 5 outcomes that could occur due to loss of FMRP function in this cell. Explain your thoughts.If a geneticist were to genetically modify a mouse strain that shows reduced calcium channel activity in presynaptic terminals and they were to measure the synaptic facilitation from these synapses, what would they expect to find? Would he expect an increased or decreased paired pulse ratio compared to one recorded from synapses of wild-type animals? Why is this the case?
- Consider a KDEL receptor that has been altered to prevent its cargo (proteins with a KDEL sequence) from dissociating (releasing) within the ER lumen. What would the result of this mutation be?During development, two neuronal axons can have different migration paths through the same brain area because the growing axons have receptors for different guidance molecules. O one of the migrating axons can only respond to long-range guidance molecules. the migrating axons have different cytoskeletal organizations in them. that brain area has only long-range guidance molecules. that brain area has only short-range guidance molecules.A Na+ 10 msec B 40mV Ca²+ C Na+ Ca²+ Each graph represents the depolarization activity during an action potential in Xenopus spinal cells at different stages of development. Referring to each electrical reading (A, B, and C), place the graphs in order of developmental stage, from earliest to latest. What are the major changes in action potential activity that occurs with development?
- 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 Testcross 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.
