Pictured is a computer-generated RNA structure tied in a trefoil knot. C. Micheletti et al. screened the several thousand RNA chains in the Protein Data Bank for the presence of knots. Only three ...

Ribonucleic acid (RNA) molecules may be best known for their job ferrying the genetic information encoded in DNA to a cell's ...

mRNA is created during transcription. During the transcription process, a single strand of DNA is decoded by RNA polymerase, and mRNA is synthesized. Physically, mRNA is a strand of nucleotides ...

DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific ...

RNA is similar to DNA but contains uracil instead of thymine (T) and has a single-stranded structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases ...

The scientist who discovered hybridization and the "other" double helix describes what it meant to biology. By Alexander Rich Fifty-two years ago I was venturing to the basement of Cal Tech chemistry ...

Failure of a gene-reading quality-control mechanism called Integrator leaves cells littered with abnormal RNA strands that ...

The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). TComparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases ...
