Brenner railway station the border, since Austria and Italy use different electrical networks (15 kV AC at 16⅔ Hz in Austria, 3000 V DC in Italy). However, the Südtirol Bahn now operate on multi-system locomotives on their Bozen/Bolzano-Innsbruck through service. There is considerable transit traffic of both passengers and goods through the station. Austria/South Tyrol Italy Cross-border In addition to passenger traffic, Brenner has seen an increasing volume of freight traffic over the past decades. The dual-track Brenner Railway was already running at full capacity as of the late 2000s; therefore, transport of freight by road has risen and consequently caused traffic congestion
Sydney Brenner concept of a messenger RNA, based on correctly interpreting the work of Elliot "Ken" Volkin and Larry Astrachan. Then, with Francis Crick, Leslie Barnett and Richard J. Watts-Tobin, Brenner genetically demonstrated the triplet nature of the code of protein translation through the Crick, Brenner, Barnett, Watts-Tobin et al. experiment of 1961, which discovered frameshift mutations. This insight provided early elucidation of the nature of the genetic code. Leslie Barnett helped set up Sydney Brenner's laboratory in Singapore, many years later. Brenner, with George Pieczenik, created the first computer matrix analysis of nucleic acids using TRAC, which Brenner continues to use.
