Answer:
A ribozyme is an RNA catalyst.
Step-by-step explanation:
Ribozymes correspond to RNA molecules with enzymatic activity, mainly catalytic. These enzymes are specific and have limited activity, unlike protein enzymes.
The action of ribozymes is to promote the hydrolysis reaction of the phosphodiester bonds of a nucleic acid, specifically RNA. These enzymes are currently very useful in molecular biology, due to their potential to manipulate RNA.
Regarding other options:
- RNA poymerase allows the construction of RNA chains, during transcription.
- Protein enzyme are the majority of enzymes involved in organic reactions, of a protein nature.
- Membrane protein are those that are integrated into the plasma membranes.
