RNA is then relegated to the intermediate role it has today—no longer the center of the stage, displaced by DNA and the more effective protein enzymes.Today, research in the RNA world is a medium-sized industry.

14/01/2018 · Describe the relative roles of DNA and RNA in protein synthesis

At the next stage, RNA molecules began to synthesize proteins, first by developing RNA adaptor molecules that can bind activated amino acids and then by arranging them according to an RNA template using other RNA molecules such as the RNA core of the ribosome.

The three types of RNA are:

messenger RNA or mRNA
transfer RNA or tRNA
ribosomal RNA or rRNA

In addition there are RNA molecules found in viruses (viral RNA) that serve as the genomic blue print that normally is encoded in DNA, and ribonucleo-proteins of diverse origin both ribosomal and non-ribosomal in nature.

By 3.6 to 3.8 billion years ago all of these events had come to pass; the RNA world had fallen and the DNA/protein world had risen in its place.But other researchers see evidence for prokaryotic cells in the first 100 million years, maybe even immediately.

This annealing of an RNA strand to its complementary DNA strand is called hybridization and plays a crucial role in the transcription and translation of genetic sequences into protein sequences.
