Based on a theoretical model such a migration mechanism may be attributed only to partial pressure differences between the leading and rear edge without the necessity of specific cell-surface adhesion [21].

These measures represent the proportional increase of G and T, respectively, on the leading strand as a result of mutational differences between the leading and lagging strands.
We describe a model to quantify the contribution of mutational differences between the leading and lagging strands in producing replication-induced skew.
