Abstract

The present invention discloses a nucleotide model device comprising two elongated bodies arranged in a DNA double helix, and further comprising a plurality of groups of connectors, wherein two ends of each connector are respectively connected to the two elongated bodies, a plurality of groups of connectors are sequentially arranged along the axis of the elongated bodies, each connector comprises two connecting posts in butt joint, the connecting posts are configured to have four different appearance marks, each elongated body comprises a plurality of sub-columnar bodies which are detachably connected, the center of each sub-columnar body is provided with a convex member, the convex member is provided with a first connecting portion, and two ends of the connecting post are provided with a second connecting portion and a third connecting portion respectively; the convex member is connected to the sub-columnar body through the detachable connection between the first connecting portion and the second connecting portion, and two sub-columnar bodies form one connector via detachable connection of two third connecting portions. The nucleotide model device provided by the present invention can be used by the learner to connect each element as required in a step-by-step manner into a final double helix model.

Description

technical field [0001] The invention relates to biotechnology, in particular to a nucleotide model device. Background technique [0002] In biological research and teaching places, especially in high school biology teaching, DNA (deoxynucleotide) models are good tools for popularizing knowledge, which can show learners the specific composition of DNA in a more intuitive and three-dimensional way. [0003] The authorized announcement number is CN 204375306 U, the applicant is Zhang Deli, and the utility model patent named "A DNA Double Helix Structure Model for Biology Teaching" provides a teaching tool, which uses a hard plastic box, and the hard plastic box. Thin iron wires connected with plastic square frames, spherical plastic sheets connected with the thin iron wires, pentagonal plastic sheets connected with the spherical plastic sheets, rectangular plastic sheets connected with the pentagonal plastic sheets, etc. Although the model can display the double helix structur...
