The cell nucleus is the site of many important biological functions of the eukaryotic cell. These processes include transcription, replication, splicing and ribosome biogenesis. The effect of these ...

- 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) ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...

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 ...

Although artificial neural networks are powerful classifiers, their internal structures are hard to interpret. In the life sciences, extensive knowledge of cell biology provides an opportunity to ...

Vesicles are small cellular containers. They perform a variety of functions, such as helping to transport materials that an organism needs to survive and recycle waste materials. There are several ...

Proteoglycans are ubiquitous molecules that function as critical components of the extracellular matrix. These proteins are composed of glycosaminoglycan chains that are covalently attached to a ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

SAN DIEGO -- Scientists at the University at Buffalo have shown that the drug methylphenidate, the generic form of Ritalin, which physicians have considered to have only short-term effects, appears to ...

The overexpression of a gene tied to cell division and the structure and function of neurons may prevent and protect against cognitive decline in both mice and humans with Alzheimer's disease (AD), ...
