Turbo-packed RNA: Turbo reagent allows precise synthesis of tRNA nucleosides
(PhysOrg.com) -- Ribonucleic acid (RNA) is a biologically important molecule that is very similar to DNA, the blueprint of life. Naturally occurring RNAs, such as transfer RNA (tRNA), contain modified building ...

Secrets of a Life-Giving Amino Acid Revealed
(PhysOrg.com) -- Selenium is a trace element crucial to life -- too little or too much of it is fatal. In the July 17 issue of the journal Science, researchers at Yale University and University of Illinois at Chi ...

Researchers reveal an RNA modification influences thousands of genes
Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics ...

Study reveals how ribosomes override their blockades
Ribosomes are "protein factories" in the cells of all living things. They produce proteins based on existing genetic codes stored on special nucleic acid molecules. These molecules, also called messenger RNA (mRNA) due to ...

Trapped in a ring: Ring-like protein complex helps ensure accurate protein production
In fairy tales, magic rings endow their owners with special abilities: the ring makes the wearer invisible, fulfils his wishes, or otherwise helps the hero on the path to his destiny. Similarly, a ring-like structure found ...

Biologists uncover a novel cellular proofreading mechanism
(PhysOrg.com) -- To make proteins, cells assemble long chains of amino acids, based on genetic instructions from DNA. That construction takes place in a tiny cellular structure called a ribosome, to which amino acids are ...

Working in concert
As cells go about the process of building new proteins, each amino acid gets delivered individually to the protein-synthesizing machinery of the ribosome by a specialized transfer RNA (tRNA) molecule. This ...

Copycat protein finds a perfect match
As proteins are synthesized during messenger RNA translation, fresh amino acids are delivered to the ribosome of the cell by nucleic acid molecules known as transfer RNAs (tRNAs). Each amino acid has a cognate ...
