one gene

one gene/one enzyme hypothesis

a general rule, proposed in 1941 by G. Beadle and E. Tatum, that each gene in a chromosome controls the synthesis of one enzyme. A modification of this idea, the one gene/one polypeptide hypothesis, accommodates the fact that all gene products are polypeptides but not all polypeptides are enzymes. A further modification, the one cistron/one polypeptide concept, accommodates alternate splicing and alternative promoter sequences.

one gene/one polypeptide

a principle that each gene in a chromosome determines a particular polypeptide. An exception allows many genes to specify only functional ribonucleic acid.

Patient discussion about one gene

Q. If being autistic relates to a disorder of genes , how does it effects in the future if one decided to have children ... does he expect to deliver those genes forward ? what are the chances for this to happen ? and what resolutions can the development of medicine offer him ?

A. it's really hard to estimate that sort of things...first of all there are more then one genes involve in that, and there is little knowledge about the part of the genes in autism. but autistic people very rarely have children of there own...
