The repressor is a dimer of a 236 amino acid subunit. Each subunit consists of two domains, one of which (the N-terminal) includes the helix-turn-helix motif and binds DNA, while the other is responsible for the formation of dimers. However, the two domains of one subunit can be separated by mild proteolysis.
The purpose of a marriage license is to provide proof that a couple is allowed to enter into a legally recognized marriage. In order to receive a marriage license, couples must provide proof of their eligibility of meeting all state requirements.
Once the marriage license is issued, the couple is free to marry within any city or town in the State of New Hampshire. A marriage certificate is a copy of the record certified by the city or town clerk or by the Registrar of the Vital Records and Health Statistics and serves as evidence of the fact of marriage. Both individuals must appear at the same time in the Office of the City Clerk.
