Ribonucleic acid definition

In recent years, the traditional definition of biocatalysts with enzymes that are proteins having catalytic functions in biological systems was expanded to a point where a series of ribonucleic acids, called ribozymes, also acts as a biocatalyst. Much effort was devoted to developing artificial ribozymes as well. In such approaches a combination of strategies to mimic ribonucleases and to simulate complementary molecular recognition of nucleic acids is essential.
