Expectations for Compilers. The first appearanceof LLVM in Xojo was when we started using itto compile and run XojoScript code 2010 Laterwe used LLVM to build iOS apps 2014 64bit apps for x86 Windows MacOS Linux and 32bit apps f Circularly Permuted Genomes. Some phages have circularly permuted genomes. This means a linear concatamer of phage DNA is synthesized, used to fill a phage head, then cut when the head is full. Generally, one head will fit more than 100% of a genome, say, 103-110%. This ensures that wherever the DNA is cut, at least one working copy of each gene is present..
