... We previously have noted that gene evolution has involved exon shuffling between protein-coding genes in the genome. A large amount of shuffling has occurred due to the prevalence of interspersed repeats in the genome. Due to sequence conservation within these regions, crossover events can take plac ...

DNA supercoil



DNA supercoiling refers to the over- or under-winding of a DNA strand, and is an expression of the strain on that strand. Supercoiling is important in a number of biological processes, such as compacting DNA. Additionally, certain enzymes such as topoisomerases are able to change DNA topology to facilitate functions such as DNA replication or transcription. Mathematical expressions are used to describe supercoiling by comparing different coiled states to relaxed B-form DNA.As a general rule, the DNA of most organisms is negatively supercoiled.
