Ribosomes, Transcription, and Translation

The genetic information stored in DNA is a living archive of instructions that cells use to accomplish the functions of life. Inside each cell, catalysts seek out the appropriate information from this ...

Under stress, bacterial RNA and proteins tell different stories

During infection, bacteria encounter rapidly changing and stressful environments inside the body. To understand how they adapt, researchers often measure messenger RNA (mRNA), which carries ...

Scientists Build a Ribosome That Reads Its Own RNA and Makes Its Own Protein

In a landmark experiment that blurs the line between the machinery of protein synthesis and the message it decodes, researchers at the University of Illinois at Chicago have engineered bacterial ...

How proteins bind to RNA: The dual mechanism of zinc fingers and disordered regions

RNA-binding proteins use a dual binding mechanism involving zinc finger (ZnF) domains and intrinsically disordered regions (IDR), reports a new study from the Institute of Science, Tokyo, Japan. Using ...

How RNA helped build life’s first proteins

A forested hill and clouds are in the background of an image of a shallow pool of steaming water, with the ground underneath colored in shades of beige, red, and brown. Life may have first emerged in ...

When protein translation fails, mechanical forces can determine how a protein gets completed

A pink ribosome surrounds part of a red-and-yellow helix-shaped strand of messenger RNA while a yellow protein branch extends from the ribosome. A graphic representation of a ribosome (pink) ...

Researchers get two genetic codes to work at the same time

Nevertheless, some preliminary steps have been taken. Researchers have managed to add some new amino acids to a bacterial cell and were able to make proteins that were one amino acid less than usual.

Cell cycle clock controls RNA methylation through a hidden ubiquitin code

A new Nature Chemical Biology study reveals that the ubiquitin ligase RLIM tags the m6A writer METTL14 with noncanonical ...

Gene Expression: Definition, How It Works, Regulation, and Uses

Definition: Gene expression is the process by which a cell turns the information in a gene into a functional product, such as an RNA molecule or a protein. In simple terms: gene expression is how a ...

Chemists show how RNA might have started to make proteins on early Earth

Chemists at University College London have shown how two of biology's most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin of ...

RNA is key to the dark matter of the genome − scientists are sequencing it to illuminate human health and disease

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...
