Aresearcher has identified a mutation in mouse cells that results in these cells having abnormally low levels of pax3 (a gene involved in muscle development) gene transcription. he determines that this is a result of a mutation affecting a promoter-proximal element. this mutation:
a. occurs upstream of the pax3 promoter.
b. may occur in a ccaat box. may occur in a gc-rich box.
c. may affect the ability of regulatory proteins to associate with pax3
d. all of the answers are correct.

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
