Montpellier Non-B DNA Day

Time: 8h30-17h00 on June 9, 2022
Location: Université de Montpellier, Campus Triolet, Salle 23.01 (see map below)

We are delighted to invite you to a one-day IN-PERSON symposium on Non-B (non-canonical) DNA, ‘the blessing and the curse’ of the genome. The research over the last decade clearly demonstrated that non-B DNA forms in living cells, is ubiquitous across the tree of life, and is important for multiple molecular processes. Non-B DNA forms transiently (at 13% of the human genome, for example!) and is involved in regulation of replication, transcription, and translation.

Register here before June 2, 2022

This event is free and open to anyone. However, to better plan the symposium (e.g., to know precisely how much :coffee: & how many :croissant: we need) we ask you to quickly complete the registration form above. Thank you for registering!

This event is sponsored by the Montpellier Advanced Knowledge Institute on Transitions (MAK’IT) and Institut des Sciences de l’Évolution de Montpellier (ISEM)
