- Xenotransplanation and problems of genetic engineering
- xenotrans. is the transfer if tissues/ cells/ organs from one species to another
- there is always a chance of rejection
- this is because proteins on surfance of transplanted cells are recognised as foreign
- scientists are devolping ways so that there is no rection
- 1:human genes from human cell surface proteins are injected into newly fertilised embryo
- 2: genes from cell surface proteins are 'knocked out' -theyre removed from the nucleus and then nuclear transfer is carried out.
- problems surrounding genetic engineering
- using antibiotic resistan genes could increase number of antibiotic resistant diseases
- using GM crops will encourage mono-culture - what if these crops fail?
- animals suffer in xenotransplantation
- GM crops will exploit farmers in poor countires
- worries that the future will bring GM humans creating genetic underclass
- xenotransplantation problems
- difference in organ size
- pigs lkifespan is 15 years, xeongraft may age prematurely
- body temp of pigs is 39 degrees
- should we kill animals for their organs?
- muslims and jews dont eat pork.
- disease transfer between species
