Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical bonds called phosphodiester bonds. Unlike DNA, RNA is usually single-stranded. Additionally ...

"The building blocks of RNA release a water molecule for every bond they form in a growing RNA chain," explains Braun, ...

The tRNA binds to its corresponding amino acid and transports it to the ribosome, where it is incorporated into the growing polypeptide chain. Ribosomal RNA (rRNA) is a component of the ribosomes, the ...

C. Micheletti et al. screened the several thousand RNA chains in the Protein Data Bank for the presence of knots. Only three knotted instances were found, though their comparison with higher ...

Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger ... amino acid to the end of the growing amino acid chain. Then the tRNAs and ribosome continue to decode ...

Genes have to be expressed in the right place, at the time, and at the right levels. Scientists wanted to know more about how ...

For the Liu Lab, necessity is truly the mother of invention. The researchers were examining how the 3D organization of the ...

TComparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases (Image: Wikimedia Commons, CC SA 3.0) The nucleotides are connected through phosphodiester bonds, ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...
