Exploring science is typically characterized by a lot of puzzles, frustrations or even failures. This weblog is mainly intended to record my working, thinking and knowledge acquisitions. I expect that some reflection would refresh my mind from time to time, and motivate me to move further, and hopefully give me a better view about even changing the landscape of bioinformatics.
You are welcome to leave some comments, good or bad, but hopefully something constructive. Enjoy your surfing!

A lack of structure facilitates protein synthesis
Texts without spaces are not very legible, as they make it very difficult for the reader to identify where a word begins and where it ends. When genetic information in our cells is read and translated into proteins, the enzymes responsible for this task face a similar challenge. They must find the correct starting point for protein synthesis. Therefore, in organisms with no real nucleus, a point exists shortly before the start codon, to which the enzymes can bind particularly well. This helps them find the starting point itself. However, genes that do not have this sequence are also reliably translated into proteins. Scientists from the Max Planck Institute of Molecular Plant Physiology in Potsdam have discovered that the structure of the messenger RNA probably plays a crucial role in this process.
