Abstract
|
|
|
1. Study was made to investigate effects of desoxyribonucleates on copper-resistance in yeast.
2. It is found that the resistant to copper is a type of mutant, which is under-grown than the sensitive in multiplication in non-copper-media.
3. In the occurrence of the resistant strain there exists the phenemic lag.
4. Desoxyribonucleate isolated from copper resistant culture is capable of inducing the resistant strain, which is the same type as donor of the resistant type. It accelerated the rate of variation to the resistant, but it is of no effect on the resistant strain.
5. Desoxyribonucleate derived from non-resistant type inhibits growth of the resistant strain ana delays the initial phase of growth. However, it is of no effect on the sensitive strain.
It is conduded that desoxyribonucleate derivea from resistant culture is capable of inducing the resistance, however, nonresistant type desoryribonucleate is of no effect on inducing the resistance.
