J. D. Salinger be a prequel to "The Catcher in the Rye". Jerome David Salinger was born in Manhattan, New York on January 1, 1919. His father, Sol Salinger, sold kosher cheese, and was from a Jewish family of Lithuanian descent, his own father having been the rabbi for the Adath Jeshurun Congregation in Louisville, Kentucky. Salinger's mother, Marie ("née" Jillich), was born in Atlantic, Iowa, of German, Irish, and Scottish descent, but changed her name to Miriam and considered herself Jewish after marrying Salinger's father. Salinger did not learn that his mother was not of Jewish ancestry until just after he celebrated
V(D)J recombination the DNA helix. Following what is known as the 12/23 Rule, gene segments to be recombined are usually adjacent to RSSs of different spacer lengths ("i.e.", one has a "12RSS" and one has a "23RSS"). This is an important feature in the regulation of V(D)J recombination. V(D)J recombination begins when V(D)J recombinase (through the activity of RAG1) binds an RSS flanking a coding gene segment (V, D, or J) and creates a single-strand nick in the DNA between the first base of the RSS (just before the heptamer) and the coding segment. This is essentially energetically neutral (no need for
