Bacterial DNA can be read either forwards or backwards - new study
E-Mail Bacteria contain symmetry in their DNA signals that enable them to be read either forwards or backwards, according to new findings at the University of Birmingham which challenge existing knowledge about gene transcription. In all living organisms, DNA code is divided into sections which provide information about a specific process. These must be read before the information can be used. Cells identify the start of each section using 'signposts', which scientists first identified in the 1960s. It has always been assumed that these signposts enable genetic sequences to be read in a si...
