What does “the cloning” mean?	The cloning is a process of creating

process of creating a copy of a particular person

or an animal.

Слайд 3 Who made the first clon?
Tong Dizhou (May

Who made the first clon? 	Tong Dizhou (May 28, 1902 -

28, 1902 - March 30, 1979) was a Chinese

embryologist remembered for his contributions to the field of cloning.

In 1963, Tong inserted DNA of a male carp into the egg of a female carp and became the first to successfully clone a fish. He is regarded as "the father of China's clone".



Слайд 4 Dolly
Dolly (July 5, 1996 – February 14, 2003),

Dolly	Dolly (July 5, 1996 – February 14, 2003), was a female

was a female domestic sheep remarkable in being the

first mammal to be cloned from an adult somatic cell, using the process of nuclear transfer. She was cloned by Ian Wilmut, Keith Campbell and colleagues at the Roslin Institute in Edinburgh, Scotland.She was dubbed "the world's most famous sheep" by Scientific American.

Слайд 6 Task 2
Answer the questions:
What are the main risks

Task 2Answer the questions:What are the main risks of cloning?What can

of cloning?
What can cloning animal show us?
What does LOS

mean?
What problems do clones with LOS have?
Are the clones really identical?
The programs for every type of different cell are different, aren't they?
What will incomplete programming cause?
Why do chromosomes get shorter?
What does “telomeres” mean?
Why are Dolly’s cells aging faster than the cells from normal sheep?


Слайд 7 Task 3
Study the text and write out the

Task 3	Study the text and write out the English equivalents to

English equivalents to the following words and expressions:
проблемы

возникают позже
клонирование животных
“синдром большого потомства”
правильно развиваться
выживать
увеличенные органы
кровоток
идентичная Днк последовательность
отклонения в развитие мозга
ослабление иммунной системы

Слайд 8 Task 4
True or false:
Cloned animals that do survive

Task 4True or false:Cloned animals that do survive tend to be

tend to be much bigger at birth than their

natural counterparts.
LOS is the "Large Offspring System".
The success rate ranges from 10 percent to 30 percent.
The clones look like the originals.
For every type of differentiated cell program is same.
Incomplete programming will cause the embryo to develop normally or successful.
As cell divide, their chromosomes get shorter.
Dolly’s cells were aging slower than the cells from a normal sheep.
To date, scientists are sure why cloned animals show differences in telomere length.

Слайд 9 Task 5
Complete the sentences with the appropriate words

Task 5	Complete the sentences with the appropriate words or word combinations

As cells divide, their

chromosomes get________.
The clones look like the originals, and their DNA sequences are ________.
Cloning animals through somatic cell nuclear transfer is___________.
Cloning animals shows us what might happen if we try to clone______________.
Cloned animals that do survive tend to be much bigger at birth than their________counterparts.
____________will cause the embryo to develop abnormally or fail.
This means that Dolly’s cells were aging ________than the cells from a normal sheep.
To date, scientists_________sure why cloned animals show differences in telomere length.
