Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • DNA is a 3D structure, and its spatial information is crucial for biological functions.
  • Existing representations of DNA sequences (textual, linguistic, syntactic) lack spatial context.
  • Understanding DNA's spatial architecture is vital for evolutionary and interaction studies.

Purpose of the Study:

  • To present a general approach for spatial representation and visualization of DNA molecules and their annotations.
  • To develop a biological 3D model for predicting the spatial trajectory of large DNA molecules.
  • To facilitate new bioinformatics studies on genome spatial architecture.

Main Methods:

  • Development of a biological 3D model to predict complex DNA spatial trajectories.
