Aribozyme is a ribozyme is a catalyst that uses rna as a substrate an rna with catalytic activity an enzyme that synthesizes rna as part of the transcription process an enzyme that catalyzes the association between the large and small ribosomal subunits

It is letter A. Ribozymes are RNA particles that catalyze synthetic responses. Most natural procedures don't occur immediately. For instance, the cleavage of an atom into two sections or the linkage of two particles into one bigger particle requires impetuses, that is, assistant particles that influence a response to go speedier.
