The N-terminus (also known as the amino-terminus, NH₂-terminus, N-terminal end or amine-terminus) refers to the start of a protein or polypeptide terminated by an amino acid with a free amine group (-NH₂). The convention for writing peptide sequences is to put the N-terminus on the left and write the sequence from N- to C-terminus. When the protein is translated from messenger RNA, it is created from N-terminus to C-terminus.

Each amino acid has a carboxyl group and an amine group, and amino acids link to one another to form a chain by a dehydration reaction by joining the amine group of one amino acid to the carboxyl group of the next. Thus, polypeptide chains have an end with an unbound carboxyl group, the C-terminus, and an end with an amine group, the N-terminus.

When the protein is translated from messenger RNA, it is created from N-terminus to C-terminus. The amino end of an amino acid (on a charged tRNA) during the elongation stage of translation, attaches to the carboxyl end of the growing or nascent chain. Since the start codon of the genetic code codes for the amino acid methionine, most protein sequences start with a methionine (or, in bacteria, mitochondria and chloroplasts, the modified version N-formylmethionine, fMet). However, some proteins are modified posttranslationally, for example by cleavage from a protein precursor, and therefore may have different amino acids at their N-terminus.

Joseph Adam "Joe" Jonas (born August 15, 1989) is an American pop singer, musician, actor, and dancer. He is a member of the Jonas Brothers, a pop-rock band made up of him and his two brothers, Nick and Kevin. He starred as Joseph Lucas on the Disney Channel original series Jonas, and released his debut solo studio album, Fastlife in October 2011.

Joseph Adam Jonas was born in Casa Grande, Arizona. His mother, Denise (née Miller), is a former sign language teacher and singer, and his father, Paul Kevin Jonas, Sr., is a songwriter, musician and former ordained minister at an Assemblies of God church. Joe is of Italian (from a great-grandfather), German, Irish, English, Cherokee, and French-Canadian descent.

On August 17, 2007, Jonas, along with his brothers, guest starred in an episode of Hannah Montana. The episode debuted alongside the television film High School Musical 2 and a sneak peek of the new Disney Channel show Phineas and Ferb. The episode broke basic cable records with a record 10.7 million viewers, and became basic cable's most watched series telecast ever.

John Dominic Crossan (born 1934) is an Irish-American New Testament scholar, historian of early Christianity, and former Catholic priest known for co-chairing the Jesus Seminar. Crossan is a major figure in the fields of anthropology of the Ancient Mediterranean and New Testament Studies, particularly in the application of postmodern hermeneutical approaches for the avant-garde Biblical studies journal Semeia.^{[citation needed]} He is also a lecturer who has appeared in television documentaries about Jesus and the Bible. He is a key figure in research into the historical Jesus.

Crossan was born in Nenagh, Co. Tipperary, Ireland.Though his father was a banker, Crossan was steeped in the rural Irish life, which he experienced through frequent visits to the home of his paternal grandparents. On graduation from St. Eunan's College, a boarding high school, in 1950, Crossan joined the Servites, a Catholic religious order, and moved to the United States. He was trained at Stonebridge Seminary, Lake Bluff, Illinois, then ordained a priest in 1957. Crossan returned to Ireland, where he earned his Doctor of Divinity in 1959 at St. Patrick's College Maynooth, the Irish national seminary. He then completed two more years of study in biblical languages at the Pontifical Biblical Institute in Rome. Thus equipped, he returned to the seminary where he had trained, and through four years of teaching he "first began to learn something about the Bible" as he puts it.^{[citation needed]} In 1965 Crossan embarked on two additional years of study, this time in archaeology based at the Ecole Biblique in Jordanian East Jerusalem. His work led him to journey through many Middle-Eastern countries before escaping just days prior to the outbreak of the Six Day War of 1967.
