What is the enzyme that makes RNA?

How is RNA made?

DNA transcription is the process by which all of the RNA within a cell's cells is created. This process has some similarities to that of DNA replication, discussed in Chapter 5. Transcription starts with the unwinding and opening of a small section of the DNA double-helix to expose each base.

Is RNA also an enzyme? Ribozymes (ribonucleic acids enzymes) are RNA molecules which have the ability to catalyze certain biochemical reactions. They can also be used to splice RNA in gene expression.

This begs the question: What type of RNA is active in enzyme activity?

Catalytic RNA RNAs that have enzymatic (specifically catalytic) activity are often referred to as "ribozymes." Roles of ribozymes include replication, mRNA processing and splicing.

Where is RNA polymerase manufactured?

The nucleolus is a specialized substructure of the nuclear nucleolus in which ribosomal RNA (rRNA), is transcribed and processed before being assembled into ribosomes. (Table 1).
