The Role of Genetics in Modern Society

Genes by definition are information we inherit from our parents, they
contain chromosomal information which codes for every physical and
mental attribute a human, animal or plant has. Modern society has come
to realise by finding the gene that causes the illness they can remove
it. They then can insert the correct gene to replace it. Genes are
arranged like beads on a piece of string, they occur in a fixed order.

Modern day society has also realised that by learning about genes and
increasing their understanding many useful tasks can be carried out.

For example, solving crimes; if a suspect has been identified, a
sample of that’s persons DNA can be checked against DNA (a long
thread- like molecule found in every living cell) which may have been
found at the crime scene. This process is done use of a genetic code.
Although every human may have the same basic components in a double
helix of DNA, base, sugar, and phosphate: The type of sugar may vary,
further more the order of complimentary base pairs may occur in a
different order. Thus, meaning an almost infinite number of
combinations. As our genes allow every person to have their own DNA
code, a definite match of DNA would mean that person could without
doubt be linked to the scene. All that is needed to extract DNA is one
cell - a speck of blood, a swab of saliva or a miniscule fragment of
skin that clings to a strand of hair!

Jack Straw is said to putting plans forward to enforce any criminal to
keep their genetic material on a national database with purpose of
cross matching with unsolved crimes.

As law stands at the moment written consent is required from the

rights whilst their victims could interpret this as being justice for

Genetic engineering is perhaps top of the media list in the
medical/biological field. This (in very simple terms) involves
swapping old genes for new ones. The topic already holds out hope for
diabetes sufferers. 2 Having type 1 or 2 diabetes increases your risk
for many serious complications. Some complications of diabetes type1
include: cardiovascular disease, retinopathy, nerve damage
(neuropathy), and kidney damage (nephropathy). Current medical
protocol means sufferers rely on insulin injections, as the Langerhans
cells in the pancreas no longer produce sufficient insulin. Genetic
engineering allows for insulin to be taken from the pancreas of cows
or pigs (although the product is impure and the body reacts with it).
By locating the defective gene, which is no easy task. However,
culturing and inserting the correct gene is a very realistic and
possible cure.
