Presentation title: Introduction to RNA
... The central dogma of genetics is that the genome, comprised of DNA, encodes many thousands of genes that can
be transcribed into RNA. Following this, the RNA may be translated into amino acids giving a functional protein.
While the genome of an individual will be identical for each cell througho ...

• Introns may play a role in gene evolution.
• In some proteins, each exon has its own
independent folding characteristics.
• Folding domains (=exons) can be grouped
together to give new proteins with new

History of RNA biology
Numerous key discoveries in biology have emerged from studies of RNA (ribonucleic acid), including seminal work in the fields of biochemistry, genetics, microbiology, molecular biology, molecular evolution and structural biology. As of 2010, 30 scientists have been awarded Nobel Prizes for experimental work that includes studies of RNA. Specific discoveries of high biological significance are discussed in this article.For related information, see the articles on History of Molecular Biology and History of Genetics. For background information, see the articles on RNA and nucleic acid.
