摘要
The stability of vesicular stomatitis virus (VSV) messenger RNA during infection of Chinese hamster ovary (CHO) cells was investigated using the temperature-sensitive mutant, tsG114. By incubating infected cells at the nonpermissive temperature (39°), RNA synthesis was blocked and VSV mRNA decayed rapidly, as determined by sucrose density gradient analysis. Each of the five VSV mRNAs was also found to decay functionally at approximately the same rate suggesting that the differential rates of accumulation of VSV mRNAs observed in vivo are due to differential rates of transcription of specific VSV genes. © 1979.
