THE DNA SEQUENCE GCGAATGAGC CONTAINING THE HUMAN CENTROMERE CORE SEQUENCE GAAT FORMS A SELF-COMPLEMENTARY DUPLEX WITH SHEARED G:A PAIRS IN SOLUTION
DNA sequence GCGAATGAGC containing the human centromere core sequence GAAT forms a self-complementary duplex with sheared G.A pairs in solution.
DNA (5'-D(*GP*CP*GP*AP*AP*TP*GP*AP*GP*C)-3')
THE SEQUENCE FORMS A STABLE TEN BASE-PAIR B-FORM DUPLEX WITH TWO PAIRS OF ADJACENT G:A MISMATCHES PAIRED VIA A SHEARED HYDROGEN BONDING SCHEME: 5' - G - C - G - A - A - T - G - A - G - C - 3' 3' - C - G - A - G - T - A - A - G - C - G - 5'
