Effect of Monovalent Cations on Type Specificity Transformation in Pneumococci

FOR investigating the mechanism of bacterial transformation we have chosen as the experimental model the transformation of the R form of Diplococcus pneumoniae type II into the mucous form of D. pneumoniae type III, by means of crude extracts of deoxyribonucleic acid, isolated from the mucous form o...

Description
Summary:FOR investigating the mechanism of bacterial transformation we have chosen as the experimental model the transformation of the R form of Diplococcus pneumoniae type II into the mucous form of D. pneumoniae type III, by means of crude extracts of deoxyribonucleic acid, isolated from the mucous form of D. pneumoniae type III. Systematic study was hampered by considerable variability in the results and by the low incidence of transformation in the control tubes.
