摘要：The sequence of the first 52 nucleotides at the 5'-end of the Q{beta} minus strand has been determined and found to be complementary in an antiparallel fashion to the 3'-terminal region of the Q{beta} plus strand. There are few similarities between the corresponding sequences of Q{beta} plus and minus strands; however, both have a hydrogen-bonded loop close to the 5'-end. The sequence of the 3'-terminal region of the plus strand was deduced: there are no termination signals within the last 32 nucleotides. A notable homology exists between the 3'-ends of Q{beta} and R17 RNA.
