Does anyone have any insight as to the implications of 10Sa RNA on the
evolution of the genetic code?
FYI: 10Sa RNA contains a tRNA-like structure with an analine attached
and a mRNA-like sequence which adds a degradation signal sequence to
truncated mRNAs that are stalled during translation...
I think that it is hard to decide whether or not 10Sa RNA is a fossil
from the RNA world or if it is a derived mechanism for eliminating
If 10Sa RNA is ancient, then what does the coupling of a tRNA- and mRNA-
molecule say about the evolution of protein synthesis in general and more
specifically about the evolution of the genetic code?
