Studies on the additivity of action of genes affecting host range in coliphage T2.

摘要: Abstract Adsorption and heat inactivation studies were made on a series of host range, turbid (ht) mutants coliphage T2H to determine the mechanisms phenotypic expression these genes additivity gene effects. The ht adsorb resistant cell B 2H at slower rate than clear h mutant; double triple with increased efficiency. Some show sensitivity compared wild type. kinetics progeny crosses discontinuity in time. Phenotypic mixing occurs respect both adsorption sensitivity. evidence supports conclusion that many mutations are controlling formation separate protein components proteins incorporated different positions external phage coat.
