1.         The following strains were obtained by the courtesy of Dr. U. Miller (University of Minnesota).

2.         The data of the analysis on cell cycle parameters are shown in Fig.1.They have revealed that the cell cycle is controlled by factor X.

3.         After 2 hr of incubation of CO₂ on an Ag (110) surface, we ended the incubation procedure.

4.         It is known that homologous recombination is the preferred mechanism of DNA repair in yeast.

5.         The effect of temperature on conductivity was examined and found not to change dramatically.

6.         Often, jewel weed can be found to grow in close proximity to poison ivy. (Two corrections needed.)

7.         Transduction efficiencies in vivo were much higher than transduction efficiencies in vitro.

8.         Upon heat activation, filament size increased, and the number of buds decreased, Both the increase in filament length and the decrease in the number of buds were only seen for cytokinin mutants.

9.         Although transition metals have the capability of forming bonds with six shared electron pairs, only quadruply bonded compounds can be isolated as stable species at room temperature.

10.     After infecting a host cell, a herpes viral DNA genome enters the nucleus where it is transcribed from DNA to RNA to both messenger RNAs (mRNAs)and noncoding RNAs (ncRNAs).
