In humans, the correlation between recombination frequency and length of dna sequence is, on average, 1 million bp per 1% re during the process of mapping the huntington disease gene (hd), it was found that hd was linked to a dna marker called g8with an rf of 596. surprisingly, when the hd gene was finally identified, its physical distance from g8was found to be about 500,000 bp, instead of the expected 5 million bp. how can this observation be explained?

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.
