This event is part of an intensive research period:
Knots and Applications.
Cellular DNA is a long, thread-like molecule with remarkably complex topology. Enzymes that control and manipulate the geometry and topology of cellular DNA perform many important cellular processes (including segregation of daughter chromosomes, gene regulation, DNA repair, and generation of antibody diversity). Some enzymes pass DNA through itself via enzyme-bridged transient breaks in the DNA; other enzymes break the DNA apart and reconnect it to different ends. DNA knots can encode important information about molecular biology in various ways.
In the topological approach to enzymology, circular DNA is incubated with an enzyme, producing an enzyme signature in the form of DNA knots and links. By observing the changes in DNA geometry (supercoiling) and topology (knotting and linking) due to enzyme action, the enzyme binding and mechanism can often be characterized. Viruses pack DNA very tightly in capsids; upon release and circularization in the globular phase, the DNA knots produced can inform about the packing geometry. DNA is also packed very tightly in eukaryotic chromosomes, and some DNA knotting and linking may be present in the chromosome organization. This workshop will have talks discussing various aspects of DNA knotting and the relationship of knotting to biological understanding.
This event is part of the 3-month intensive research period program on “Knots and Applications”, that takes place at the Centro di Ricerca Matematica "Ennio De Giorgi" of the Scuola Normale Superiore di Pisa, Italy, and that is organised in collaboration with INdAM.
