How Does Replication-Associated Mutational Pressure Influence
... In fast-dividing cells, the copy number of proximal genes can be up to eight times higher than that of distal genes (Cooper and Helmstetter 1968). This reflects the topology of replication when the cell cycle is shorter than the time needed for replication of the whole chromosome. Nevertheless, it i ...

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.
