regulate other proteins by adding phosphate groups. bind to them, switching them on and off. binds to cyclin D, moving cells from G1 to S. At the G2/mitosis border, a combines with another cyclin (cyclin B). Phosphorylation occurs, bringing about a series of changes in the nuclear membrane via caldesmon, cytoskeleton, and .

Which layer will become saturated first when rain falls?

Describe how a non-resistant staphylococcus aureus bacterium can produce a bacterium that is resistant to methicillin

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.
