RNA serves a multitude of functions within cells. These functions are primarily involved in converting the genetic information contained in a cell's DNA into the proteins that determine the cell's structure and function. All RNAs are...

The letters RNA stand for ribonucleic acid, a type of nucleic acid. There are two types of nucleic acid--DNA (deoxyribonucleic acid) and RNA.DNA carries a cell's genetic information, but this information cannot be accessed without RNA. In some...

Ribonucleic acid (RNA) conveys genetic information and catalyzes important biochemical reactions. Similar, but not identical, to a single strand of deoxyribonucleic acid (DNA), in some lower organisms, RNA replaces DNA as the genetic material. As with...

Ribonucleic acid (RNA), generally abbreviated RNA, is an organic chemical substance in living cells that plays several essential roles in the transfer of genetic information from one generation to the next. The hereditary information itself is...

Ribonucleic acid or RNA is a nucleic acid, consisting of many nucleotides that form a polymer. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate. RNA plays several important biological roles, including many processes...

New multiplex labeling technique fills gap between in situ hybridization and microarray analysis Scientists at the University of California, San Diego, recently described a novel combination of new and preexisting technology that permits them to visualize five RNAs simultaneously in a single cell.1...

MicroRNAs: An emerging portrait What can we learn from the in-process encyclopedia of how non-protein-coding sequences exert genetic control? Over the years, scientists and drug companies seeking genetic control over biological systems have focused their attention on proteins. But that's only one...

Dr. Arthur Kornberg, a biochemist who received the 1959 Nobel Prize in physiology or medicine for the test-tube synthesis of DNA, died of respiratory failure Friday at Stanford Hospital. He was 89.Kornberg, an active professor emeritus of biochemistry at Stanford University's School of Medicine, shared...
