The roles of almost all these RNA genes have yet to be understood.

Out of this work has come the idea that the first genomes were made of RNA genes.

The RNA genes surviving today maight be all that remain of this early condition.

The toxic effects of the protein are neutralised by the RNA gene.

It has 4,346 protein genes and 169 RNA genes.

These RNA genes are about 300 nucleotides in length.

One task is to catalog how many regulatory RNA genes exist in the cells of various species.

These turned out to be silencing RNA genes.

The gene has characteristics of both protein and Non-coding RNA genes.

This has clearly been the case for histones and ribosomal RNA genes.
