Quotes About RNA

A small segment of DNA that encodes a gene is transcribed into a snippet of RNA, which then travels to the manufacturing region of the cell. There this "messenger RNA" facilitates the assembly of the proper sequence of amino acids to make a specified protein.

But she became more interested in DNA's less-celebrated sibling, RNA. It's the molecule that actually does the work in a cell by copying some of the instructions coded by the DNA and using them to build proteins.

some forms of RNA could likewise be enzymes. Specifically, they found that some RNA molecules can split themselves by sparking a chemical reaction. They dubbed these catalytic RNAs "ribozymes

Thomas Cech (pronounced "check") of the University of Colorado in Boulder, who was using X-ray crystallography in order to explore each nook and cranny of the structure of RNA.

Doudna's mission when she arrived at the University of Colorado as a postdoc was to map the intron that Cech had discovered could be a self-splicing piece of RNA, showing all of its atoms, bonds, and shapes.

Nature isn't benign," Lederberg said at the meeting's opening. "The bottom lines: the units of natural selection—DNA, sometimes RNA elements—are by no means neatly packaged in discrete organisms. They all share the entire biosphere. The survival of the human species is not a preordained evolutionary program. Abundant sources of genetic variation exist for viruses to learn new tricks, not necessarily confined to what happens routinely, or even frequently.

RNA interference has proven to be a quite reliable mechanism for turning genes off in a whole variety of different plants and animals.

In my first publishable research, I obtained evidence that the replication of polio viral RNA engendered a multi-stranded intermediate, although my description of that intermediate proved flawed in its details.

It seems likely that most if not all the genetic information in any organism is carried by nucleic acid - usually by DNA, although certain small viruses use RNA as their genetic material.

In most life forms, genes are stretched out along the length of a filament-like molecule of DNA, deoxyribonucleic acid. But many viruses—including influenza, HIV, and the coronavirus that causes SARS (severe acute respiratory syndrome)—encode their genes in RNA, ribonucleic acid, an even simpler but less stable molecule.

Influenza is an RNA virus. So are HIV and the coronavirus.

The amount of DNA not coding for RNA, sometimes called junk DNA (a dangerous term for something one does not understand), is also much greater in eukaryotes.
