Description
Technical field
This utility model relates to a kind of teaching demonstration instrument, is specifically related to a kind of DNA demonstrating teaching apparatus.
Background technology
Biology is a research biosis and science of vital movement rule, and the duplication of DNA, transcribes and translate
The understanding of rules such as (central dogmas) is the basic of understanding vital movement.The duplication of DNA in teaching material, transcribe and be translated as static map
Solve, the most readily understood for middle school student or abecedarian, therefore use dynamic DNA demonstrator to replace figure static in teaching material
Solution description contributes to student and recognizes biosis from whole removing, holds the substitutive characteristics of vital movement rule.Especially in education
The mountain area that facility falls behind, because projector, the shortage of the auxiliary equipments such as microscope, teaching aid and model seem more in teaching process
Important.
Designer, according to produced problem actual in bioconversion medium and learning experiences, sets through pondering deeply amendment repeatedly
Meter, last half a year and produce one can be vivid show the biodynamic mistake such as central dogma and aminoacid dehydrating condensation
The Self-made Realia model of journey helps Students ' Learning, and its base panel also attaches monoamino-acid codon synopsis and central dogma
Schematic diagram guidance convenient to operate.
