The functions of biomolecules, including lipids, nucleic acids and especially proteins are determined to a great extent by their structure. This structure–function relationship is a foundation of many ...

Fowler showed that tropomodulin's function is critical for development of the heart and blood cells, and for proper function of many cells and tissues, including eye lens, neurons in the brain, ...

A team led by UT Southwestern Medical Center researchers has uncovered the atomic structure of a protein complex pivotal to the function of motile cilia, the hair-like structures extending from the ...

- 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) ...

Cryo-electron tomography shows what molecules look like in high-resolution – in this case, the virus that causes COVID-19. Nanographics, CC BY-SA All life is made up of cells several magnitudes ...

Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment ...

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, ...

The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...

Investigators have created computer-generated models to bridge the gap between 'test tube' data about neurons and the function of those cells in the living brain. Their study could help in the ...

What does it take to be a super athlete? Take a close-up look at cells, tissues, and organs to see if their biology gives them an advantage.
