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 ...

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists ...

In a recent study published in the journal Nature, a large team of researchers from the United States (U.S.) used single-cell ribonucleic acid (RNA) sequencing combined with high-resolution ...

The list below offers a representative sample of the courses you can expect in the study of cellular and molecular biology at DePauw. From theoretical foundations to practical experiences, these ...

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, ...

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.

RNA in cells performs an astounding number of functions. Messenger RNA carries the sequences of active genes to cellular machinery that turns it into proteins. And transfer RNA molecules are an ...

Researchers discovered a kinase-driven phosphorylation switch that activates DNA packaging machinery, aligning nucleosomes at ...

An essential component of the lymphatic system, the thymus, a pyramid-shaped organ located in the thoracic cavity, is responsible for producing T-cells. For centuries, the thymus was believed to be an ...
