GENETEIC MODIFICATION AND BIOTECHNOLOGY

Now let's look at some methodologies that are used for different purposes and have opened up new perspectives mainly in the fields of medicine and agronomy, but they have also created a lot of controversy and deserve to be thoroughly evaluated, because they represent a double edged sword.

But first you must known what do the restriction enzimes are. 

DNAPROFILING OR DNAFINGERPRINT

DNAprofiling also known as DNAfingerprint is a methodology which is now widely used in paternity testing and in criminal investigations. It consist basically of comparing some sections of DNA that are unique to each person.

GENE TRANSFER

Gene transfer consists of inserting a specific gene from an organism into another organism, so that the modified organism (GMO or transgenic) is able to sinthesize a protein and therefore to express a characteristic that was not its own.

Homework: Go to BioNinja site, read the secction about  GMO's debate and take note from their benefits and risk. Then explain what you think about it, giving reasons that support your opinion. You can also read page 51 from your study guide book.

NATURAL AND ARTIFICIAL CLONING

Clones are groups of genetically identical organisms derived from a single original parent cell. 

Cloning multicellular organism requires the production of stem cells that can be artificially generated from adult tissue using a process known as somatic cell nuclear transfer (SCNT)

Now see page 52 from your study guide book and read the last section, "investigating factors afecting rooting in stem cuttings".
