Input (English): of these was found to repair lacZ transcripts in E coli, and that trans-splicing one was also used to correct mutated p53 transcripts. One of these contains loops A and B and helices H1 through H4, and is useful in the formation of a 2,3-cyclic phosphate. That example, originally found in the tobacco ringspot virus, is called the Hairpin one, and in that virus the same gene codes for one of these important in the replication of some viroids. Another example is found in the Hepatitis delta virus. Discoveries about the activity of these in cleaving and splicing nucleic acids led to the 1989 Nobel in Chemistry for Sidney Altman and Thomas Cech. For 10 points, name this type of nucleic acid including the Hammerhead one which can catalyze a reaction.
Output (English): Science
