An international team of molecular chemists, physicists and nanomolecular scientists has found the molecule responsible for the bright, white-colored stripes sported by the Pacific cleaner shrimp. The study is published in Nature Photonics. Diederik.....»»
Structural insight into process of gene regulation
In the cell nucleus, numerous proteins bind to the DNA molecule in order to regulate the activity of certain genes. One of these is the TATA-box binding protein (TBP), which binds to a specific DNA sequence and constitutes an initial signal for the r.....»»
A fast and efficient method for detecting microRNAs
In the early 1990s, scientists who were studying the development of a roundworm identified a small RNA molecule that regulated the expression of specific genes. This marked the discovery of microRNAs (miRNAs), which are now known to be present across.....»»
