Cloning
A
Science Research Paper
Has someone went
and said “I just want to make another me, and send him to do my job” or “Have
another me do my homework”. Those expressions are everywhere from television to
today’s hardworking citizens. There is a solution though called Cloning, where
you can replicate the same organism with the same genes and everything,
basically a pair of Artificial Twins. Cloning is a difficult process of large
proportions, but how does it work?
What is cloning? Cloning is the creation of
an organism that is an exact genetic copy of another. This means that every
single bit of DNA is the same between the two! So if took two cows and clone
them, they would be the exact same in every way. A cloning method, known
as "somatic cell nuclear transfer" or simply "nuclear
transfer," requires two kinds of cell. One is a “somatic” cell,
which is collected from the animal that is to be cloned (known as the
"genetic donor").
A somatic cell is
any cell other than a sperm cell or egg cell, and contains the complete DNA, or
genetic blueprint, of the animal it came from. For cloning purposes,
somatic cells are typically obtained by a “routine skin biopsy” performed by a
veterinarian.The scientist stimulates the fused egg, which
"activates" the egg and causes it to divide just as an egg would if
it had been fertilized by a sperm cell in conventional reproduction. The
activated egg is then placed in a culture medium.
As cellular
division continues over the course of several days, a blast cyst (early-stage
embryo)is created. After about a week, an embryo transfer specialist moves
the “blast cyst” to a recipient female (Also called a "Surrogate
Mother") where it continues to develop. After a full-term pregnancy,
the “Surrogate Mother” gives birth to an animal that is essentially the
identical twin of the genetic donor.
So Cloning, a
difficult process, even for the smartest people can have trouble understanding
the physics of Cloning. Will there be a time where human cloning can exist, and
clone somebody, or is the Government going to keep illegalized what cannot be
done yet? And now, those expressions can become a reality
