RESUMO
The DNA coding for RNase H from a mutant strain of Escherichia coli (FB2) was cloned into plasmid pBR322. DNA sequence analysis and the exchange of a portion of the mutant and wild-type genes revealed that a single-base alteration (C→T) in the coding region of the structural gene for RNase H is responsible for the difference in RNase H activity of the wild-type and mutant cells.
