These chains come in a wide range of lengths. In humans a typical protein is about 400 amino acids long; some are a lot longer. Molecules of RNA, one of the two nucleic acids, can reach up to 100,000 ...

DNA holds our genetic blueprints, but its cousin, RNA, conducts our daily lives I n 1957, just four years after Francis Crick ...

Proteins are essential biological molecules that perform a vast array of functions crucial for life, from catalyzing ...

RNA molecules carry instructions from DNA for making proteins that carry out much of the work of living cells. Knowing where these molecules are located in complex tissues is a critical part of ...

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 ...

Many writers grouse when an editor makes a change in a story, but the consequences of changing a single word usually aren’t that dire. Not so with genetic instructions for making proteins. Even a ...

When a bone grows, our bodies’ proteins help provide the structure. When a muscle tears, proteins help rebuild it. When we fight an infection, transport oxygen in our blood or send messages to a cell, ...

A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein ...

The ocean can be a cold place to call home. Mammals like seals stay warm by enveloping themselves in a layer of thick fur and blubber. Cephalopods — the group of (mostly) ultrasmart mollusks that ...
