DNA DOUBLE HELICAL STRUCTURE MODEL CAPABLE OF ENHANCING UNDERSTANDING ABOUT A DNA DOUBLE HELICAL STRUCTURE AND INCREASING A LEARNING EFFECT

摘要

PURPOSE: A DNA double helical structure model is provided to be easily de-assembled and assembled and to show morphological property and functional property of DNA by faithfully expressing DNA double helical structure.;CONSTITUTION: Nucleotide members(100,200,300,400) comprises chain units(110,210,310,410) and base units(120,220,420). The chain unit is extended as a fixed length. The base unit is extended from the inner side of the chain unit. The chain unit of the nucleotide member is combined to the chain unit of the other nucleotide member. The base unit of the nucleotide member is combined to the base unit of the other nucleotide member. A coupling part of the two nucleotide members in which the chain unit is combined is able to be bent in the inner side direction of the chain unit.;COPYRIGHT KIPO 2012
