As I understand, if scientists produced a
human clone, there would be a great risk of it having a disease. Nobody seems
to understand the ageing process of a clone. It would be terrible if a baby was
the age of its parent at 31 .
Its cells would grow old fast and it would die young.
32 until the technique is perfectly safe, it should
be 33 .
I'd love to have a clone of 34 .
I often wish I had a twin sister, someone who 35 me
in everything. So why not a clone? Well, the idea 36 be
fun but I'm not sure if it would be 37 .
I think we would be playing with fire if we let scientists go ahead with 38 cloning.
There are so many 39
involved that all research in this area
should be strictly controlled.
There are so many arguments 40 cloning
that it is difficult to get anyone to consider the possible benefits. I am 41 that
it is a technique which could be beneficial. The most obvious use would be for
childless 42 . They would be
able to have babies with their own genetic material. I don't see what's wrong
with that.
Imagine a child 43 up
knowing that his or her mother is really a sister or a brother. The emotional 44 on
the child would be 45 . Or a
child who was cloned from a dead brother or sister. What kind of emotional
pressure would they feel, knowing they were made as a replacement for another?
The whole idea
46 me!
It's all very good to ban human cloning but
scientists should be allowed to 47
research. If they don't, we may 48 important
benefits for our society, such as producing body organs. A clone is an 49 copy
of a person with the same gene. Therefore, it is the 50 donor
for an organ(器官)
transplant.
