Objectives


All should know reasons why science
uses genetic engineering



Most should understand the 2 mainline
genetic research



Some could answer GCSE questions
on the subject

Journey


1
-

learn some new words to help
understand the whole subject



2
-
Reflect on the science of genetics



3
-

why it raises moral issues (religious
and non religious)

Objectives


Keywords to copy



1
-
stem cell:


2
-
embryos


IVF:


cloning

reasons why science uses genetic engineering


In groups discuss and write down reasons why
we use genetic engineering (at least 4 reasons)



Genetic diseases affect large numbers of
people. Defective inherited genes can cause
mental retardation, physical deformity or early
death. Scientists are involved in genetic
research into: cystic fibrosis, muscular
dystrophy, sickle
-
cell anaemia, taysachs disease
and huntigton’chorea as well as other diseases
like alzeimher’s…etc

2 mainline genetic research



Scientist have been helped by the human
Genome
project
, which is mapping all the genes
in the human body (3:33)



Most genetic research are based on two things


1
-

changing the information that is passed down
from one generation to the next:
Germline gene
therapy

or


2
-

removing/altering genes from embryos so
that they are born healthy (
pre
-
implantation
genetic diagnosis

Question


Who do you think should regulate all
these research:


1
-

An independent body of religious
people


2
-
An independent body of scientist


3
-
A consultation group of mixed people


4
-
The Law


5
-

Tony Blair or Gerry Wadwa

Homework


Read through worksheet on Christian
attitudes to genetic engineering and
answer all questions.


Science behind the genes


In Britain there is a scientific process called
the “cybrid”



they are human
-
nonhuman cytoplasmic
hybrid embryos or for a simple explanation a
human nucleus in an empty animal egg
making an embryo which is 99.9% human


This was voted by the UK parliament and is
used by scientist for stem cell research

Understanding the morals and the
issues


In groups A and C, in 6 minutes prepare
and present various


Non religious arguments in favour of
genetic engineering



In groups B and D, in 6 minutes,
prepare and present various


Non religious arguments against
genetic engineering

Compare your answers to the
following


1
-
Non religious arguments in favour of genetic
engineering


It offers the prospect of cures for currently incurable
diseases.


It is done in some countries and is therefore
available to the rich already


Cloning have been used to grow healthy cells to
replace the malfunctioning one successfully


Cloning using cybrids does not involve any loss of
human life


Genetic research is part of medical research. It is
bound to evolve and include genetic engineering


It is already monitored by law and has vast potential

And again


2
-

Non religious arguments against genetic
engineering


There is too little information about the long term
consequences


It has effects which would be irreversible.


It places too much power in the hands of scientist
who could act like doctor frankeinstein


It treats the human body like a commodity


It offers the possiblity of people being screened out
of life insurance, senior positions…because they
may die young or may have a degenerative diseases
..etc


GCSE practice



a/ What is cloning? (2)


b/ Do you think cybrid are the future for
human genetics? give two reasons for your
point of view (4)


c/ Explain why some people think genetic
engineering and cloning for medical research
are wrong (8)


d/ ”Jesus would heal people so we have a
right to use any means necessary to heal
humans even genetic manipulation”


i Do you agree? Give reasons for your
opinion (3)


ii Give reasons why some people may
disagree with you (3)


Where will it end?



Although the public are largely on side on
the use of genetic engineering to help cure
illness or provide transplant organs, there is
still an overwhelming resistance to parents
creating "designer babies". Only 13% of
respondents to the ICM survey said they
were in support of the parent's right to use
genetic engineering to design their unborn
child, with 63% opposing the process.
However, a higher 20% of 18
-
24 year olds
said they would condone the practice, which
suggests perhaps that future generations will
be more open to the idea
