Clones and recently the remains of several well-preserved mammoths

Clones are organisms that
have identical DNA, and therefore, they are exact genetic copies of one
another. Identical twins are an example of natural cloning. Cloning can also
happen in the lab using modern day cloning technology.

            “There are two ways to make an exact copy of an organism
in a lab; artificial embryo twinning and somatic cell nuclear transfer”(Learn.Genetics).
Artificial embryo twinning requires less technology, but still allows the
ability to create clones or identical twins. The technique basically mimics the
natural process that creates identical twins. The way natural twin’s form is
very early in development when the embryo splits in two. Twinning happens in
the first few days after egg and sperm join, while the embryo is only made up
of tiny cells. Each half of the embryo continues dividing on its own,
eventually separating into complete individuals. Artificial embryo twinning is
similar, but the early stages are carried out inside a Petri dish instead of
inside the mother. A very early embryo is separated into individual cells,
which divide and develop over time, and are then placed inside the mother for
later development. Quite a few cells end up developing in the Petri dish, and
are placed inside the mother, so the mother carrying, could end up with 6+
offspring if they all survived, but usually only two survive.

            Somatic cell nuclear transfer (SCNT), also known as
nuclear transfer. This technique uses a different approach than artificial
embryo twinning, but it produces the same result: an exact genetic copy of an
individual. Basically, “the nucleus is removed from a healthy egg, and this
becomes the host for a nucleus that is transplanted from another cell. The
resulting embryo can be used to generate embryonic stem cells with a genetic
match to the nucleus donor, or can be implanted into a surrogate mother to
create a cloned individual”(hemi).

            The first animal to be successfully cloned was a sheep named
Dolly, who was born in 1996 and died in 2003. She is on display at the national
museum of Scotland, Edinburgh. So far, cattle, chickens, dogs, cats, horses and
several other mammals have been cloned. There has even been talk about cloning
a wooly mammoth, which went extinct around 10,000 years ago. “Global warming
has caused thawing in permafrost regions in eastern Russia, and recently the
remains of several well-preserved mammoths have been found”(Genetics
generation). However for the cloning to work, the mammoth DNA would need to be
in near-perfect condition. The cloning of mammals can be very beneficial to
society, because they would never go extinct and there would be an endless
supply of food.

            Cloning has many benefits, one being a solution to organ
limitation. There are many people today needing organs to survive, and they are
not available a lot of times. Cloning of human organs would be very beneficial
to humanity, because it would prevent unnecessary deaths, and people would not
need to wait long periods of time for available organs. There are many other
benefits including cures for cancer and the next steps to immorality. It will
just take time for technology to improve to be able to successfully implement
these ideas.
