Use "ribozyme" in a sentence
"The ribozyme was the template, and was self-complementary."
"The alternative hypothesis to autocatalysis by catalysis via ligation or other reactions is the hope to form an RNA enzyme, called a ribozyme, that can act as a "polymerase" enzyme able to catalyze the template replication of any RNA, by sequential addition of nucleotides that are Watson Crick complements of the template strand."
"There must exist some mechanism for manufacturing the enzyme (or other biological catalyst, such as ribozyme), and that mechanism must be subject to mutation capable of altering the structure of the enzyme."
