RNA molecules differ from DNA molecules in several important ways ... being expressed in a cell at a particular point in time. Ribosomes are the sites in a cell in which protein synthesis takes ...

The surprising paradigm shift could lead to much more protective sunscreens and effective skin treatments.

Ribosomes are themselves composed of a complex ... Other proteins play roles in DNA replication and transcription. Yet other proteins provide structural support for the cell, create channels ...

Messenger RNA carries genetic information from DNA in the highly protected nucleus out to the rest of the cell, where structures called ribosomes can build proteins according to the DNA blueprint.

RNA polymerase enzymes read the DNA sequence and synthesize messenger RNA (mRNA) molecules, which carry the genetic information to the ribosomes for protein synthesis. translation is the process by ...

We have all been told to avoid direct sunlight between 12 noon and 3 p.m., seek out shade and put on sunscreen and a hat.

New research from the University of Copenhagen and NTU Singapore reveals that RNA damage, rather than DNA, plays a primary ...

Study reveals UV radiation damages RNA, not DNA, triggering skin inflammation and cell death through ribotoxic stress response.

Bacteria modify their ribosomes when exposed to widely used antibiotics ... including mutations in their DNA. Another common mechanism is their ability to actively pump and transport antibiotics ...

The two strands of the DNA helix are unzipped by breaking of the ... of mRNA is now ready to leave the nucleus and travel to the ribosome. After translation, the polypeptide is finally folded ...

This transfer of life's code from DNA to RNA is called transcription. Next, a ribosome uses the message encoded in RNA to build proteins—the molecules performing most of the essential functions ...
