Preimplantation signalling system discovered in human embryos
Human embryos can show an innate immune response when exposed to pathogens, as early as day five, researchers in the UK have found...
Gene expression is the process of converting the information contained in a gene into the gene product. The DNA of the gene is first transcribed into RNA, which is then either translated into a protein or remains as an RNA molecule. The expression level of a particular gene can be turned ’up’ or ‘down’ in different cells at different times, as required.
