5. How did Pax6 work to produce fly eyes after mouse Pax6 was engineered in? A. Pax6 coded for an exon that expressed eye structure.B. Pax6 coded for a transcription factor that turned on eye genesC. Pax6 coded for a cis-factor that controlled eye genesD. Pax 6 controlled alternative splicing equally in flies and mice

How did Pax6 work to produce fly eyes after mouse Pax6 was engineered in? The answer is that the fruit fly genome does not include the genes needed to make mouse eyes. Mouse Pax6 protein induces fly eyes because of the downstream genes affected by Pax6 – which is a transcription factor , those that function later in the process of eye development. Transcription factors like Pax6 interact with their target genes by binding with short DNA sequences adjacent to the gene, usually at the 5' end, called cis-regulatory elements . These regulatory elements are located in the promoter and help determine whether the adjacent DNA is transcribed.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
