History

• 1.1966- the establishment of the complete genetic
  code. In 1966, some scientists crack the genetic
  code. The cracking of the genetic code opened the
  door for the explosion of genetic engineering
  studies and achievement.
• 2. 1970-first restriction enzyme isolated. In
  1970, two scientists called Howard and David
  working independently isolated the first
  restriction enzyme. The restriction enzyme called
  Reverse Transcriptase, cut DNA molecules at
  precise locations. This capability led to the
  manipulation of DNA.
• 3. In 1996, Dolly, the first animal cloned from
  adult cells, born. Researchers at the Roslin
  Institute in Scotland created Dolly using a
  technique similar to that with which they created
  the first sheep from differentiated embryo cells
  in 1995.
• 4. In 1997, a Harvard graduate researcher,
  Richard, announced that he planned to clone a
  human being before any federal laws could be
  enacted to ban the process. His announcement
  irritated lots of ethical people.

Interview

• Introduce
• What is your opinion about cloning?
• Are you for the idea of cloning which helps the
  parents who are unable to have their own baby to
  carry out their dreams?

Discussion

• A Is cloning wrong or right?

-Wrong- ?The decline in genetic diversity. ?If
everyone has the same genetic material ?If a
population of organisms has the same genetic
information ? Errors are occurring when
scientists carry out the procedure.
-Right- ? The goals and proposes for cloning
range from making copies of those that have
deceased to better engineering the offspring in
humans and animals. ? Cloning could also directly
offer a means of curing diseases or technique
that could extend means to acquiring new data
for sciences of embryology and how organisms
develop as a whole over time. ? Researchers can
harvest and grow adult cells in large amounts
compared to embryos. ? Scientists can then
genetically alter these cells and find which ones
did transform and then clone only those cells.

• B Can we and should we clone humans?

There is no doubt that many problems
involving the technological and ethical sides of
this issue will arise and will be virtually
impossible to avoid, but the overall idea of
cloning humans is one that we should accept as a
possible reality for the future. Using
cloning to procedure offspring for the sake of
their organs is an issue that we must also face
and question whether or not it is morally right.
Most people only seem to want to carter to
their own needs and do not bother to consider the
consequences society and the clone may have to
face.
