Embodiment Construction
[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0045] A 3D intelligent simulation method for phage infection of bacteria, the method comprising the following steps:
[0046] 1) Making a phage infection model
[0047] 1.1) Make a phage model, such as figure 1 Shown: the phage protein shell 1 is made by 3D printing, a red LED light 2 is installed on the top of the phage protein shell 1, and a yellow LED light 3 simulating phage DNA is installed on the top of the phage protein shell 1. The phage model includes the parent phage model 4 and the offspring phage model 5, and the volume of the parent phage model 4 is larger than that of the offspring phage model 5.
[0048] Phages are divided into mild and virulent phages according to their infectivity. Potent T phage: the structure is generally tadpole-shaped, the head contains double-stranded DNA molecules, the neck is a hollow needl...

The invention discloses a 3D intelligent simulation method for phage-infected bacteria. The steps are as follows: 1) making a phage-infected model; 2) designing a control circuit for the phage-infected model; 3) dividing the phage-infected bacteria into a process of potent phage infection and mild phage infection process; strong phage infection process includes: a) press S2, the yellow LED light on the parental phage model lights up, lights up for 1 second and then turns off, and the yellow LED lights on the support plate light up sequentially for 1 second Then turn off, and simulate DNA injection into the bacteria; b) press S2, the yellow LED light and purple LED light on the progeny phage model will flicker in a period of 1 second, and turn off after 5 seconds; c) press S2, the assembled state; d ) Press S2, the slider and the progeny phage model come out of the bacteria, releasing the state. This method effectively integrates the two parts. The motor and LED lights are controlled by the AT89C51 single-chip microcomputer to realize the dynamic process cycle and the persistence of any state, so that the teaching content of the bacteriophage infecting bacteria is more complete.
Description
technical field [0001] The invention relates to a phage-infected bacterium experiment, in particular to a 3D intelligent simulation method for phage-infected bacteria. Background technique [0002] "Phage Infection Bacteria Experiment" is the content of "DNA is the main genetic material" in Chapter 3, Section 1 of "Biology. Compulsory 2. Inheritance and Evolution" published by the PEP. The experiment uses the isotope labeling method to allow students to understand the whole process of virus reproduction in bacteria, so as to draw the conclusion that DNA is the main genetic material. The experiment is relatively abstract, and it is difficult for students to understand it. The textbook focuses on explaining the five processes of virulent phages infecting bacteria, while the process of forming lysogens from mild phages infecting bacteria is arranged in Topic 1 Genetic Engineering of "Biology. Compulsory 3. Topics of Modern Biotechnology". The two parts of strong phage infecti...
