1 Gene technology involves altering the genes in an organism, which is then said to be genetically modifi ed. 2 The usual way of genetically modifying bacteria is to insert a plasmid containing the desired gene into them. 3 The steps involved in the production of bacteria capable of synthesising human insulin...

There are social implications related to using genetically modified organisms in food production.modified crop plants become agricultural weeds and invade crop habitatsintoduced gene(s) may be transferred by pollen:             - to wild relatives --> more invasive hybrid offspring ...

Genetic technology can provide benefits in, for example, agriculture and medicine, but has the associated risk of the escape of the gene concerned into organisms other than the intended host.Herbicide resistant cropsFields of crops are sprayed with herbicide to kill weeds that compete for space, light, water, and ions...

Gene therapy: treatment of a genetic disorder by altering a person's genotype (insert functional alleles of genes into cells)Common vectors:virus: retrovirus, lentivirus, HIV, adeno-associated virus (AAV)liposomes - small spheres of phospholipidsnaked DNA- retrovirus: inserts genes randomly into host's genome. If the gene...

Genetic engineering is improving the quality (nutrition) and yield of crop plants and livestock  --> therefore is solving the demand for food in the world1. Golden Rice- genetically modified rice produces large quantities of β-carotene in endosperm --> human cells convert β-carotene to Vitamin A- Golden Rice...
