Why are microorganisms useful for making products on an industrial scale? (5 things)
Reproduce rapidly, have plasmids, biochemistry is quite simple, can make complex molecules, no ethical concerns

Outline the stages in genetic modification
The gene needed for desirable protein is isolated. Gene replicated to make copies, then the genes are joined to vector (a carrier for the gene) which are transferred into new cells. Not all new cells are modified,so choose successfully modified indi

How do you take a DNA sample?
Take a blood sample which contains lots of white blood cells. White blood cells then isolated and DNA is tested for genetic disorder

What is a gene probe?
A strand of bases that is complementary to the faulty gene you are looking for
7 of 11
How can you use a gene probe to see if someone has a faulty gene?
If the gene is present the probe will stick to the DNA strand- the bases will lock perfectly together
