2) Arm (Bio-531/534,536) ¥ Spacer(Bio-541/544,549,550) Put the Arms and Spaces upwards alternately into the Shaft. Put a Spacer (longer one Bio-541 is desirable) after the last Arm and fasten firmly with Plain Washer (Bio-572), Spring Lock Washer (Bio-573) and Hexabon Cap Nut. (Bio-571) (Fig-5) Each Arm has protrusions on top and underside. Place the Spacers to fit the protrusions. Use Hexagon Nut (Bio-574) if there remains a loose space at the threaded end of the Shaft. Fig. 5 The Arms thus assembled will form as follows, when viewed from above.	Fig. 3 (Left) / Fig. 4 (Right) Arms and Spacers are made up to the above specifications Fig. 6
DNA-A : The Arms form a helical configuration, clockwise in helical progression, in which adjacent Arms are displaced successively around the axis by an approximate angles 32.73�‹and the 11th Arm takes the same direction with that of the bottom positioned Arm. DNA-B : Forming a helix configuration clockwise, displaced 36�‹, and the 10th Arm takes the same direction with bottom positioned Arm. DNA-Z : Forming a helix configuration counter-clockwise, displaced 30�‹, and 12th Arm takes the same direction with bottom positioned Arm(Fig6). Double Helices RNA : Forming same as DNA-A. Triple Helices DNA : Forming a helix configuration clockwise, displacaces 30�‹, and 12th Arm takes the same dirsction with bottom positioned Arm.
