It’s widely known that numerous of physiological and biochemical processes within cells are accomplished by protein. A tiny cell can contain millions of proteins which are translated and synthesized by ribosome. However, after synthesis, these protein molecules often have to undergo post-translational modification, which has important biological significance. Ubiquitinylation is one type of post-translational modification. In other words, after “dressing up” by some “junior partners”, proteins were sent for “mission”….

Month-end Check: Biotech study topics in Nature-August
Caution urged over editing DNA in wildlife (intentionally or not) A work describing the use of a gene-editing technique to insert a mutation into fruit files that would be passed on to almost all of its offspring has brought the concern about bioengineering in to a more fierce debate. A lot of scientists feel uneasy about this study: what if the engineered creature escaped from the lab? The mutation might…
