Heizer's "Double Negative" and Smithson's "Spiral Jetty" — one a privation, the other an accretion — form an essential pair in the canon of twentieth-century sculpture.
Why should I destroy my life, my brain, and my health to innovate and let some asshole come along and steal it from me?" Heizer's "Double Negative" and Smithson's "Spiral Jetty" — one a privation, the other an accretion — form an essential pair in the canon of twentieth-century sculpture.
From a more practical and pedagogical standpoint, these times of great uncertainty make a strong case for two approaches that may at first seem contradictory but are actually an essential pair: intellectual rigor and intellectual flexibility.
Ypk1 and Ypk2 are an essential pair of homologous kinases and members of the AGC kinase family (Roelants et al. 2004).
This analysis also helps elucidate the role of pyridoxine, an essential vitamin that has no direct effect on biomass, since pyridoxal phosphate is a cofactor that binds two genes (glyA and CD2834) part of the same essential pair.
Ent1 and Ent2 are an essential pair of clathrin adaptor proteins whose epsin N-terminal homology (ENTH) domains bind PtdIns(4,5 P2 and play a crucial role in signaling to the polarity-regulating GTPase Cdc42 (Wendland et al. 1999; Aguilar et al. 2006).
