Proteins carry out many of an organism's critical functions, and they are coded for by genes. To make a protein from a gene, a cell first needs a copy of the gene in the form of a molecule called RNA.

Two recently published studies led by Brazilian scientists reveal the key roles of multifunctional proteins, STIP1 and Maspin ...

DNA- and RNA-binding proteins (DRBPs) constitute a significant fraction of cellular proteins and have important roles in cells. Their functions include control of transcription and translation, DNA ...

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

Several years ago, biologists discovered a new type of genetic material known as long noncoding RNA. This RNA does not code for proteins and is copied from sections of the genome once believed to be ...

Jeremy Berg does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their ...

Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

In 2015, researchers at UC San Francisco found a structure inside of tumor cells that biologists had never seen before. Even more surprising, a closer examination of the structure revealed that it ...

Every function in a cell is associated with a particular protein or group of proteins, typically in a well-defined ...

ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus. Because of the presence of unstable, high-energy bonds ...
