Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...
How does a cell know when it’s been damaged? A molecular alarm, set off by mutated RNA and colliding ribosomes, signals danger. When the sun shines on your skin, what does it hit? When it causes a ...
RNA is one of the bodies most vital molecules, and it comes in a few forms. For example, messenger RNA fills an essential role in gene expression by copying the sequences of active genes, which are ...
A metabolic enzyme studied for over seven decades has a hidden second function—it can unwind RNA and promote cell cycle progression, an additional function beyond its role in energy production, ...
An interdisciplinary research team from two working groups at the Center for Synthetic Biology at TU Darmstadt has developed ...
The United States Food and Drug Administration has just approved the first-ever clinical trial that uses CRISPR-Cas13 RNA ...
A laboratory test — or assay — developed in Sudbury, Ont., to measure the effectiveness of chemotherapy is one step closer to ...
The natural RNAi mechanism can be directed by either short interfering RNA (siRNA) or microRNA (miRNA). 1 There are four key steps in the RNAi pathway. When miRNA acts as the guide for RNAi, only a ...
Almost 40,000 years ago, a juvenile woolly mammoth died in modern-day Siberia. Today, its long-frozen remains have yielded the oldest sequences of RNA—messenger molecules that carry out genetic ...
