Gene is the material basis of heredity, a general term for specific nucleotide sequences with genetic information on DNA molecules, and DNA molecule fragments with genetic effects. All life phenomena such as birth, growth, disease, old age, and death of organisms are related to genes. It also determines the internal factors of human health and is closely related to human health.

Transgenic technology, including the cloning of foreign genes, expression vectors, receptor cells, and transgenic pathways, etc. The artificial synthesis technology of foreign genes and the artificial design and development of gene regulatory networks have led to the transformation of transgenic technology in the 21st century towards synthetic biology. era.

1. What are genes?

"Gene" is the basic unit of inheritance in an organism. It exists on the chromosomes of cells and is arranged in a straight line. The more popular genetic engineering now is a genetic technology: with the help of biochemical means, the genetic material in the cells of one organism is taken out, cut and reassembled in vitro, and then introduced into the living cells of another organism to Change the genetic traits of organisms or create new species of organisms. The development of "pig body and human heart" in the text belongs to genetic engineering. Gene-related "cloning" means not using the normal fertilization and reproduction methods in nature, but using asexual reproduction to copy a group of offspring with identical genetic traits. This technology was first successfully researched and tested by the Roslin Institute in Edinburgh, Scotland, UK.

2. What does this article mainly cover?

The main content of this article is to describe the award-winning process of "I" and other scientists for successfully transcribing human heart genes into pigs to create pig-body and human hearts, and then boldly envision the future applications of pig-body and human hearts. prospect.

3. Please divide the text into paragraphs.

The text has a total of 8 natural paragraphs, which can be divided into three parts.

The first part (1, 2) is about "I" driving home after winning the award, eliciting the following thoughts.

The second part (3-6) describes the process of "I" using genetic technology to conduct medical and biological experiments, and makes bold predictions and imaginations.

The third part (7, 8) confirms that the genetic imagination will soon become a reality.

4. What thoughts does the author have on the prospects of genetic technology?

Surgeons can easily perform heart transplant surgery on heart patients. Medical experts can prepare the most suitable genetic heart for the patient in advance. Some treatments for heart disease could significantly extend human lifespan.

self-guided exploration

1. What role does "a naive pig engraved on the medal" play in the structure of the article?

It sets the stage for the following, which triggers the imagination of the genetic development of "pig body and human heart", and the natural use of flashback techniques makes people feel real and credible.

4. Some of the experiments and examples described in the article are facts and some are prospects for the future. Please find them separately.

Facts, the third paragraph talks about his work and why he wants to deal with pigs; prospect, the sixth paragraph gives scientific imagination about the development of genes.

collaborative inquiry

1. Has genetic technology been successfully applied to humans so far? Why? Do you still have confidence in this technology? Give reasons.

No, because animal genes have strong rejection reactions and cannot be applied to humans. There are also "certain pig viruses that can be transmitted to humans", causing "the plan to be suspended." We are confident because any technology has a long process from invention to application. For example, when the train was first invented, it was ridiculed because it was not as fast as a horse-drawn carriage, but now the horse-drawn carriage cannot compare with it.

2. Do you think this article is vividly written? Please find sentences that you think are well written and give reasons.

To describe the piggy’s reluctance to be alone, in the third paragraph, the words “listless”, “sullen” and “depressed” are used, which are very literary and vivid. Some sentences are written very playfully and full of life, such as in the sixth paragraph, "You don't have to worry about it. Our products are guaranteed to last for forty years." In the third paragraph, "Pigs are also very considerate. They like to cuddle up. At your feet, there is kindness and kindness, never irritability." In paragraph 6, "Medical experts can tailor clothes for their patients better than the most amazing designers in the world."

3. Do you think the author’s imagination is reasonable? Can you find any basis for it in the text?

It's not groundless, it has theoretical basis and the facts described in paragraph 5.

Expand and extend

1. What benefits do you think mapping the genome will bring to humans?

Help the patient find out the cause of the disease. Gene-identifying drugs can be produced to reduce patient suffering. Develop the economy, produce genetically modified food, etc.

2. What is your experience after reading this article? What did you learn from the article? Please feel free to talk about it.

Tip: You can be guided from the following aspects, and the answers do not have to be unified.

(1) What do you think of the author’s serious attitude towards scientific research?

(2) What inspirations can you get from the author’s courage to actively imagine?

(3) What did you see from Hardy and Bailey? What inspiration did you get?

(4) Once the code of life is deciphered, in addition to bringing benefits to mankind, what else do you think it will bring to people’s lives?
