Abstract:
In a recent paper, we have put forward the hypothesis that there exist smart purposive mechanisms - tandem repeat length managers - which regulate the length of some tandem repeat, or cause rearrangements, and are almost always driven by some variable number tandem repeat. We have called the framework in which such mechanisms act 'dynamical genetics'. The purpose of this paper is to contribute to lay the foundations of a molecular study of the above mechanisms, by proposing a hypothesis, based on various kinds of supporting evidence and plausibility arguments, about the special importance of DNA quadruplexes for dynamical genetics, and by considering the involved enzymes. This hypothesis states that a tandem repeat length manager acts almost always by monitoring a DNA tract that has the characteristics of being a variable number tandem repeat and/or forming a DNA quadruplex, and that it is almost always driven by at least one of them.

Gene Duplication and Divergence
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.

Comparing Copy Number Variations and SNPs
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
