Because this element binds to the alpha phosphates of dNTPs, buffers used in PCR require the addition of this element as a cofactor for DNA polymerase.
This element tightly binds to NMDA receptor pores and acts as an ion channel block. This element is often used to prevent seizure convulsion in eclampsia. Because this element binds to the alpha phosphates of dNTPs, buffers used in PCR require the addition of this element as a cofactor for DNA polymerase. After oxygen, this element makes up the greatest percentage of the mantle by weight. ATP is nearly always found coordinated to this metal, which is also a component of Grignard reagents. A chlorin surrounds an ion of this element in chlorophyll. For 10 points, name this alkaline earth metal located above calcium on the Periodic Table, with symbol Mg.
