Sentence examples for efficiency of transformation of from inspiring English sources
However, only 25 40% of hygromycin-resistant colonies yielded a yellow color, indicating a high rate of spontaneous hygromycin resistance when M. avium is transformed at 32°C, with a final efficiency of transformation of 1 8 × 102 transformants per μg of DNA.
The high sensitivity of the rods by comparison with the cones may be a reflection of the greater concentration in them of pigment that would permit them to catch light more efficiently, or it may depend on other factors e.g., the efficiency of transformation of the light energy into electrical energy.
This phenomenon is probably related to the increased efficiency of transformation of rat cells by B77 virus observed with virus rescued from transformed rat cells [ 15].
Therefore, we can infer that R288 is necessary to communicate the cooperative response to the neighboring protomer to enhance the efficiency of transformation of the R5P substrate.
In either explanation, the apparently low efficiency of transformation of Shimaa strains with DNAs from unrelated strains might reflect a relative inability to acquire foreign (e.g., European) DNA during human infection, which, in turn, might make Amerindian strains less able than European strains to adapt to variable host conditions, and thus less fit.
It is well known that linearizing a circular DNA plasmid markedly reduces its efficiency of transformation of bacteria.
Our data indicate that DSB mediated by I- SceI in T. reesei improves the efficiency of transformation and the stability of the transformants and promotes gene targeting at a defined locus.
Luminescence efficiency depends on the degree of transformation of excitation energy into light, and there are relatively few materials that have sufficient luminescence efficiency to be of practical value.
Plant transformation vectors and methodologies have been improved to increase the efficiency of transformation and to achieve stable expression of transgenes in plants.
