1. Ask for high-quality poems about cloning

Two "Clone" poems

Cloning

Life is not a pity

But it is precious because of love

If life and love are destined not to last forever

Then let it be cloned continuously!

Clone me and clone you

Clone our love

In the new life and love

I am willing to sleep forever Wake up

Two

If I can't meet you in this life

Maybe I was born too early

p>

And you haven’t been born yet

Then I will clone me

I can’t predict when you will be born

But I will continue Clone yourself

Until

Not sooner or later

You and I meet at the age of eighteen 2. List sentences about cloning in daily life that do not include Dolly the sheep was cloned in 1979, crucian carp was cloned in 1979, Xenopus was cloned in 1960 and 1962, black-spotted frog was cloned in 1978, and Dolly the sheep was cloned. In July 1995, Scottish scientists successfully cloned using the embryonic cells of a ewe. Got two sheep.

In February 1997, Scottish scientists cloned the sheep "Dolly" using tissue removed from the udder of a 6-year-old ewe. This is the first time in human history that a mammal has been successfully cloned.

In July 1997, Scottish scientists cloned the sheep "Polly" using somatic sheep cells grown in a laboratory and implanted with a human gene. In July 1998, researchers at the University of Hawaii in the United States used the cells of one experimental mouse to clone 50 experimental mice for three generations. 3. Ancient poems and agricultural proverbs about phenological phenomena and content about cloning

1. Ancient poems:

Phenology is the germination, flowering, fruiting, withering of plants and the migration of certain animals, Activities such as hibernation reflect changes in climate and seasons. From this perspective, ancient Chinese poetry contains extremely rich phenological knowledge.

For example, "Three or two branches of peach blossoms outside the bamboo, ducks are prophets of the warmth of the spring river." (Su Shi wrote Huichong's "Evening Scene on the Spring River") In the early spring weather, ducks are the first to sense the warmth of the spring river and play in the water.

"In the cold weather, the water birds rely on each other, and they are a group of ten and a hundred, and the light falls. No pedestrians can get up when they pass by, and suddenly they hear the sound of ice and fly together." (Qin Guan's "Returning from Guangling") In late winter, The water birds depend on each other, and the sound of ice makes the birds fly away in fright. Ducks and birds are both messengers of spring.

"It rains every house during the yellow plum season, and there are frogs everywhere in the grassy pond." (Zhao Shixiu's "Water Threshold Reminds the Heart") The three objects appearing in the poem show the seasonal characteristics of the late spring and early summer when the plums are yellow and ripe.

Huang Chao's "Inscription on Chrysanthemums" said: "The rustling west wind fills the courtyard with plants, and the pistils are cold and fragrant, and the butterflies are hard to come." The chrysanthemums withered and the butterflies disappeared. Although there is no word "Autumn", the coolness of autumn is still there. But it came to my face.

3. In several places, early orioles compete for warmth in the trees, while new swallows peck at the new mud. Cue the coming of spring.

Two:

"Many agricultural proverbs handed down from ancient times contain rich phenological knowledge." For example:

△ Hearing cicadas chirping in the rain predicts the arrival of sunny days.

△In the morning, the earthworms hear the cicadas chirping, and in the evening, they welcome the rain.

△The sparrows are hoarding food and want snow to fall.

△It will rain in the ant nest.

△The fish dives into the water, and the rain is coming.

△Swallows fly low to make rain fall.

△The toad comes out of its hole and the rain is steady.

△ Turtle back tide, sign of rain.

△Earthworms crawled on the road, and the rain made it messy.

△The loach is quiet and the weather is sunny.

△The pig is holding the grass in its mouth, and the cold wave is coming.

△The chickens stay late, the ducks crow happily, and the wind and rain will come soon.

What is cloning? Cloning is an emerging biotechnology for asexual reproduction. In the section "What is cloning", the author makes this science and technology easy to understand

First of all, starting from common biological phenomena that are easy for us to understand, "a bacterium clones itself in about 20 minutes" It can be divided into two; a grape branch cut into ten sections may become ten grapes... All of these are organisms that reproduce by dividing themselves into two or by expanding a small part of themselves. It’s asexual reproduction.” This makes the profound science and technology vivid and clear

Next, tracing the original meaning of “clone” from its etymology allows us to further understand the meaning of cloning. Following the previous article, the article introduces cloning further, starting from plant "cloning" to animal "cloning". It ends with "Sun Wukong often pulls out a handful of monkey hairs at critical moments to create a large group of monkeys. The monkey hairs turn into monkeys, which means cloning monkeys." Science and technology are written in an interesting way

Before and after the birth of the cloned crucian carp.

This section is a brief introduction and explanation of the cloning experiment

The author of this section does not write the cloning experiment in chronological order, but uses two clues to organize the material: one is based on Chinese and foreign scientific experiments as a clue , written like this, highlights the research results and contributions of Chinese scientists in cloning experiments; one is to arrange the materials based on the experimental subjects, from fish, amphibians to mammals, as clues. Written in this way, it is easier to understand the development of cloning technology. The two clues are organically combined, which greatly enhances the explanation effect. 4. Does anyone have good words and sentences to describe ‘cloning’?

I learned from extracurricular books that cloning technology is now available. As long as a person takes out a cell from a plant, animal, or human, he or she can clone a person or thing exactly like him or her. I think that if I become a cloning expert, I will definitely clone many things that are beneficial to mankind.

If I could clone, I would definitely clone more and more trees on the earth. I want every mountain village, every city, and the endless desert to be covered with green. Moreover, the tree I cloned is a fast-growing tree. This kind of tree can grow into a big tree within half a year, making the earth full of green trees and full of flowers. It remains unbeaten all year round, making the earth always a vibrant scene. At this time, I believe that our earth will become more beautiful and lovely.

If I could clone, I would clone many rare animals. Such as giant panda, Siberian tiger, crested ibis, alligator, etc. In addition to rare animals, I also want to clone many rare plants, such as ginkgo, metasequoia, ginseng, etc. Let them not only grow in every corner of the motherland, but also spread throughout other places on the earth, so that the term "rare animals and plants" will automatically disappear. By then, how beautiful the global village will be!

If I could clone, I would clone all those knowledgeable and kind-hearted people who are no longer alive and make them exactly the same as before.

However, if I want to make all of this a reality, I must learn the skills in a down-to-earth manner and work hard to realize this ideal.

5. Famous quotes about the negative effects of cloning

It is good for learning. Although human cloning has many disadvantages

it can also help many people who are infertile to realize their dreams

p>

The scientific community now divides cloning into two types: therapeutic cloning and reproductive cloning. The former uses embryonic stem cells to clone human organs for medical research and to solve the problem of insufficient donors for organ transplantation. This is an issue in the international scientific community and ethics. It is supported by the academic community, but there is a premise that the embryos used for therapeutic cloning cannot exceed the limit of 14 days of pregnancy. As for reproductive cloning, commonly known as human cloning, because it violates bioethics in general principle, therefore, the mainstream opinion of scientists is firmly opposed. UNESCO, the World Health Organization, the International Human Genome Ethics Committee and various governments have also made it very clear that they oppose reproductive cloning
