Who was Jack the Ripper?
Picture of Aaron Kosminski
What actually happened?
1888; a horrific time in British history, the brutal
stabbing of several prostitutes by the serial killer
known as ‘Jack the Ripper’ occurred. At the time
of the murders the resources to fully uncover the
man behind the crimes were not available. So
today in 2158, we are doing our best to establish
the truth using the most sophisticated equipment
we have accessible. Having access to DNA
samples of three suspects and one piece of viable
evidence made it easier to determine which would
be the most accurate offender.
Through this investigation we have received extraordinary results
revealing the notorious killer. Jack the ripper has been exposed to be
suspect number 2, the Polish Jew, Aaron Kosminski. The results of the
electrophoresis have revealed that the DNA from under the victims’
fingernails is a match to Aaron Kosminski’s mouth swab DNA.
The face of Jack the Ripper has now been uncovered and the decades of
demanded questions have now been answered.
The three main suspects in the Jack the Ripper investigation were Montague
John Druitt, Aaron Kosminski and Michael Ostrog. Cells obtained from the
cheeks of each of the suspects gave us the opportunity to collect DNA found
in the nucleus. Inside each nucleus there is about two meters of DNA we can
use to analyse. There are multiple techniques used in determining different
aspects of the investigation. Polymerase chain reaction (PCR) can also be
used when copies of a specific DNA sequence are needed and Gel
Electrophoresis can be used when DNA needs to be sorted according to
length. Further down in this article, a full explanation of the process used to
determine the killer, and whom we think is the most accurate answer.

Cloning is the creation and formation of an organism
that is an exact copy of another organism. Meaning
that every single bit of DNA is identical between the
two. Cloning is performed to produce a copy or copies
of an organism, manipulate, divide and mutate
different organisms. Some other reasons to clone are:
Jack the Ripper exposed...
After cutting the DNA to specific sequences, we separated the different sized
fragments to compare the suspects and victim. To separate the different sized
fragments of DNA, we used a process called electrophoresis. When DNA is cut
with the restriction enzymes we are left with a mixture of fragments of different
lengths. Electrophoresis is used to sort out the fragments into groups, depending
on length. The DNA is then cut up into Fractions. The fragments are then
placed into the wells at one end of the gel. The Gel is exposed to an electric
field, with the negative charge at the origin and the positive at the opposite end.
The DNA carries a negative charge and therefore moves toward through the gel
towards the positive pole. The DNA fragments will move at different rates,
shortest fragments the fastest and the longer fragments will move more slowly.
The result of this process is a series of parallel bands at various distances from
the wells. These bands can be used to compare DNA, therefore determining the
murderer in this case.

Reviving Endangered or Extinct Species
Cloning animal copies for research. Much of
what researchers have learnt about human
diseases comes from studying animals such as
Cloning for medical purposes
Cloning stem cells for research, for repairing
damaged or diseased organs and tissues.
So far a large variety of animals have been cloned, such as camels, carp,
cats, cattle, deer, a dog, ferrets, frogs (tadpoles), fruit flies, goats, gaur,
horses, mice, mule, pigs, rabbits, rats, a rhesus monkey, water buffalo and
wolves. Although there is an upside being able to clone animals and
organisms, the side effects cloning has is, with the cloning of Dolly the
sheep, several deaths of embryos and newborns before the success of the
achievement was made. If a human being was to be clone it is not
guaranteed to survive and develop normally. Several other side effects of
cloning are that it could cause unbalance to society, also lead to extinction
and diseases to not only humans, but the more humans cloned the more
resources are going to be needed which could cause extinction to animals
and resources. Cloning goes against nature and the process of the human
