The whimsy of scientists: gene gun

This is a photo of genegun invented by scientists. After nearly a hundred years of hard work, scientists have used lenqin Ray's diffraction images to establish a correct genetic concept, which has never been shaken. The diameter of gene molecules is only 2 nm, 10 thousand times smaller than that of Silk. How can we deal with them? It is indeed a big problem.

When you contact scientists for the first time, you will find that their eyes are very dull (not good at speaking) and they are not easy to return to the real world, as if they are always thinking about something. Genetic scientists are indeed very laborious.

Plants are a type of non-mobile organisms, and their cells also contain genetic genes. For example, we take rice as an example to determine whether it can resist drought, tolerate saline-alkali soil, prevent pests, prevent diseases, resist herbicide, and even add nutrients to produce protein required by humans. This idea is very good, but how can we make rice obedient? Answer: replace genes.

In, scientists at Cornell University in the United States designed a device to implant growth hormone (Hormones) genes into the heritage of the target plant, called it "genetic shooting ". This is the origin of the gene gun name.

Rice Planting is very labor-intensive, and the process of seeding, transplanting, irrigation, and spraying herbicide should not be less. Transgenic Rice saves time and effort, and gains a lot. Why not?

Note: Based on the current technological level of humans, we cannot independently create genes, but only transfer genes to create so-called "transgenic ". The transgenic technology is not simple, and will not be used by anyone without knives or scissors.
