Our knowledge of the structure of the cytoplasm has grown with the advent of advanced techniques and equipment that have allowed us to study cellular components. Over the past 150 years, such advances ...

Figure 1: The G-quadruplex structure-specific antibody, BG4, binds with high affinity to RNA G-quadruplex structures. Here we show that a G-quadruplex-specific antibody, BG4 (ref. 4), binds to RNA ...

We have used size-fractionated, fluorescent dextrans to probe the structure of the cytoplasmic ground substance of living Swiss 3T3 cells by fluorescence recovery after photobleaching and video image ...

The current coronavirus disease 2019 (COVID-19) pandemic has claimed over 1.9 million lives so far, and scientists have been racing to develop vaccines that will curtail its spread. Most of these ...

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life.
