Ex Input:
Seas of calcite predominate during times of low concentration of this element. The NIMS probe discovered that Ganymede has a sulfate of this element, which is also used to treat eclampsia. Its molten form is used to make metallic titanium in the Kroll process. The active site of rubisco contains a carbamylated lysine attached to an ion of this element. Its cationic form is used to stabilize the product of PCR, and it is also prevalent in certain reagents in a Schlenck equilibrium. It is found in Grignard reagents as well as coordinated to the porphyrin ring of chlorophyll. For 10 points, name this element with atomic number 12 and symbol Mg.

Ex Input:
His death, called providential by Charles Sumner, fell on the same day his home state abolished slavery. After both Louis McLane and William Duane refused to pull the government's funds out of the Second Bank of the United States, the duty fell to this man in his role as Jackson's Secretary of the Treasury.

History

Ex Input:
L1 ligase one of these objects was developed by Robertson and Elington. One of these objects creates a five prime lariat cap, increasing the half-life and therefore the fitness of a homing endonuclease. That object occurs in the gene I-DirI and is called the GIRI branching one. One of these objects is found in tobacco ringspot virus and is called "hairpin," and the B6. 61 one of these can add twenty nucleotides to a primer template before decomposing. The best known of these has invariant positions G12 and G8 serving as general base and general acid and can cleave between one base and an A, C, or U base. Many of these entities require divalent metal cofactors like magnesium, and most of them conduct their own hydrolysis or hydrolysis of similar structures, like the best-known Hammerhead one. FTP, name this class of RNA enzymes.
