EACH OF OUR CHROMOSOMES, IS MADE OF TWO, VERY LONG, COILED CORDS, OF HUMAN GENES, ON THE LEFT, IS A PICTURE, OF HOW, OUR CHROMOSOMES LOOK. THEY ARE HELD TOGETHER, IN THE MIDDLE, BY A THICK RING, CALLED A CENTROMERE, MADE OF CREATINE, CREATININE AND PROLINE
	EACH CORD, HAS A THICK, OUTER PROTECTIVE PROTEIN COATING, SURROUNDING,THE INTERTWINED, THREADS OF MOLECULES, OF DNA. THAT CONTAIN, OUR GENES. THE COATING, IS 35 TIMES WIDER, THAN THE WIDTH, OF THE PAIRED, TWISTED THREADS, OF DNA MOLECULES, AT THE CENTER.
WHEN A CELL, IS FULLY GROWN AND IS TOLD TO DIVIDE, INTO 2 CELLS, IT BEGINS, TO FORM, THE LONG COILED CORDS, THAT YOU SEE ABOVE, THAT CONTAIN, TWO LONG, ENTWINED CORDS OF PAIRED DNA MOLECULES, AT THEIR VERY CENTER. VERY OFTEN, THE TWO DNA MOLECULES, ARE CALLED, DOUBLE HELIX MOLECULES. WHY ARE THEY CALLED....DOUBLE....HELIX MOLECULES ? WE KNOW ALREADY, THAT A HELIX,  IS A SPIRALING, COILED UP FORM, LIKE A COIL SPRING.
	THEREFORE, YOU CAN UNDERSTAND,THAT, A DOUBLE HELIX, IS SIMPLY, TWO LONG COILS, ONE NEXT TO THE OTHER, JUST AS YOU SEE, IN THE DRAWING, LEFT, THAT SHOWS A, GREEN CORD, COILED AROUND THE  BLUE CYLINDER AND A , RED CORD, COILED NEXT TO THE GREEN CORD.
NOW, YOU KNOW....THE DNA DOUBLE HELIX, IS SIMPLY... THE TWO LONG, COILED, MOLECULES OF DNA, AT THE CENTER,OF OUR COILED UP, CHROMOSOMES. NOW,  IF YOU WANT TO KNOW WHY, IT IS CALLED DNA...CLICK ON PAGE 3
