Making insect-resistant plants - Answer-A gene responsible for making a toxin that kills
insects is isolated from a ground-dwelling bacterium and is inserted into plants, using
vectors

Genetic engineering in bacterial cells - Answer-Bacterial cells have been genetically
engineered to produce useful substances such as human insulin to treat diabetes

Making insulin - Answer-A gene responsible for making insulin is isolated from cells of
the human pancreas and is inserted via vectors into bacteria that can rapidly reproduce

Use of enzymes in genetic engineering - Answer-Enzymes are used to isolate a
required gene from an organism with a desirable characteristic

Use of vectors in genetic engineering - Answer-The isolated required gene is inserted
into a vector, which is then used to insert the gene into the required cells

Vectors - Answer-Bacterial plasmids or viruses that can transfer DNA from one
organism to another

Bacterial plasmid - Answer-A small ring of extra DNA found in bacterial cells, plasmids
are cut open with enzymes and an isolated gene is inserted into them

Virus - Answer-A non-living infectious agent that releases genetic information into a host
cell to replicate itself, isolated genes can be inserted into a virus which can copy it into
