(a)
To describe: The gene which is likely to act earlier in the pathway responsible for the development of vulva.
Introduction: Vulva is an opening in the mid of the body of C. elegans. Eggs are laid through this opening, and this opening is formed during the developmental stages of the larva.
(b)
To determine: The
Introduction: Initially, the gonadal anchor cell is determined, and then the second round of cell-cell interaction is initiated, which leads to the formation of the vulva. This interaction involves the cells which are present in gonads and the precursor cells.

- Researchers investigated the step-by-step processes of cell differentiation in somites through experiments in which cells were transplanted from one location to another early after somite formation. What did these experiments show? The cells of a somite are determined as the somite matures in response to cell-to-cell signals. The cells of a somite are irreversibly determined as soon as the somite is formed, based on cell-to-cell signals. The cells of a somite are determined as the somite matures in response to internal cytoplasmic signals. The cells of a somite are irreversibly determined as soon as the somite is formed, based on internal cytoplasmicarrow_forwardWhen BRCA1 is absent, is it unable to transcribe genes like p21, which leads to senescence ?arrow_forwardLateral inhibition and induction are key processes in embryonic development. Discuss two different signalling pathways involved in these processes,arrow_forward
- The slow block to polyspermy involves a permanent modification of the egg surface, usually through exocytosis of the cortical granules. In the 1970s, Dave Epel carried out experiments that led to the conclusion that a Ca2+ rise in the egg is both necessary and sufficient to trigger cortical granule exoctyosis (CGE). For the experiment below, describe it as correlation, loss-of-function or gain-of function. Then, indicate the predicted result. Experiment (a) – Dr. Epel injects the egg with an indicator dye that fluoresces when Ca2+ binds to it. In unfertilized eggs, there is no fluorescence and no CGE. However, when sperm are added to the eggs, he observes fluorescence and then CGE.arrow_forwardIn neurulation, what cell types are involved? What morphogens are present (and antagonists)? What transcription factors are there? What tissues/tissue types are there? What are the signaling pathways used and how do each function? What's the end goal, and what is the response in development? Draw a labeled diagram or detailed flow chart of neurulation in embryos to show this.(FYI, this is one practice question. No grading involved.)arrow_forwardGradients of morphogens can be preestablished in the oocyte. Also, later in development, morphogens can be secreted from cells. How are these two processes similar and different?arrow_forward
- Explain why axis-determination is a crucial aspect of embryonic development. Explain how maternal-effect genes encode cytoplasmic factors that play a role in axis determination.arrow_forwardWhat are morphogens? Explain how they influence tissue patterning during embryonic development. Describe TWO specific examples to support your explanation.arrow_forwardWhat are the molecular switches involve in sporulation? explain the switches involved not the stages. molecular switches are different from sporulation stages.arrow_forward
- The BMP-Nodal gradient so vital to amphibian and fish development may be critically important in other vertebrates (including humans) as well. Moreover, can any field of pluripotent cells (such as human embryonic stem cells)respond to gradients of BMP and Nodal signals?arrow_forwardWhich of the following is NOT a true statement? (Check all that apply) A Prior to migration, all neural crest cells undergo EMT. B) Prior to migration, trunk neural crest cells undergo MET. C) All neural crest cells differentiate into their final derivatives at the site of their induction. D Neural crest cells are functionally equivalent to multipotent stem cells. E) The neural crest is specified where Wnt induces BMP and is then turn off. F The cranial neural crest contributes to the development of the tooth. G) All neural crest cells migrate dorsally from their induction site. H) Early migrating trunk neural crest cells are specified to become melanoblasts. O Ventrally migrating trunk neural crest cells that are responsive to Wnt and NT3 will become glial cells if they express Notch. Cranial neural crest cells all migrate ventrally from their site of specification.arrow_forwardExplain the reason why in the absence of Delta, cells become unsynchronized and somites are not formed completely.arrow_forward
