Teaching demonstration model for bacteriophage invading bacteria

Abstract

The invention relates to an emulational teaching model for demonstrating how a bacteriophage invades bacteria, in particular to a teaching demonstration model for a bacteriophage invading bacteria. The teaching demonstration model comprises a T4 bacteriophage model and an escherichia coli thallus model. The T4 bacteriophage model is composed of a protein head module and a hollow protein tail module, and a bacteriophage DNA molecule module is included in the protein head module. The escherichia coli thallus model is composed of simulative flagellums, a capsule, a cell wall module, a cell membrane module, an escherichia coli DNA molecule module, a ribosome module and a cytoplasm module, small holes are formed in the capsule, the cell membrane and the cell wall of the model, and therefore the NDA molecule module of the bacteriophage model can move into the escherichia coli thallus model conveniently. Multiple rails facilitating the moving of all the modules and a baffle hiding the protein shell of the model are arranged on the base plate of the whole model and the cytoplasm module.

Description

Technical field [0001] The invention relates to a teaching demonstration tool, in particular to a simulation teaching device for demonstrating how phages invade bacteria. Background technique [0002] At present, the materials used for teaching demonstration of bacteriophage invading bacteria are all written narratives or simple schematic diagrams, which make the teaching objects difficult to understand, or even if they understand, they may not have a deep memory, and teachers need to use them in the process of demonstration. Computers, projectors and other facilities, once there are problems with these facilities, they cannot be demonstrated. Summary of the invention [0003] The present invention takes a real object as a model, and in the course of teaching, the teacher can interact with the students to get rid of the blunt text description. Students can operate the whole process by themselves, which can not only generate a strong interest in learning, but also deepen the intui...
