Explanations and differances for somatic and germ line gene therapy by Ben S.NCS
| Question | Answer |
|---|---|
| Gene therapy is the treatment of _______ ________ | Genetic Disorders |
| Gene therapy involves the use of molecular _______ __________ techniques. | Genetic Technology |
| Any cell forming the body of an organism (Body cells) are known as _______ | Somatic |
| The sperm, egg, zygote and unspecialised cells of early embryos are known as ____ ____ cells | Germ line |
| Somatic cell gene therapy involves Augmentation - where an absense of a gene product is solved by engineering a funtioning copy of a gene and inserting it into a specialised cell resulting in _______ _________ of the absent polypeptide | Protein synthesis |
| The working allele copies are inserted into the gene by liposomes which are __________ ________ | Artificial vesicles |
| Somatic treatment is short lived due to the specialised cells containing the gene not ________ and passing on the allele | dividing |
| Getting the alleles into the genome is difficult. Gentically modified _______ may be used, as well as Liposomes, however these can prove inefficient and the body may become immune to the vector. | viruses |
| The ethical reasons against somatic cell gene therapy is _______ as the manipulations are restricted to the parent and will not effect their children. | limited |
| With Germ line treatment the allele is placed into the germline cells, it is long lived aa the functional allele is placed into ____ _____ | stem cells |
| Germ line treatment is easier to perform, although there are ethical issues about ________ the human genome | altering |
