Summary
This conference explored chromatin assembly and organization, integrating insights from structural biology and live-cell dynamics. Experts discussed how chromatin moves from self-assembly to self-organization principles.
Area of Science:
- Molecular Biology
- Biophysics
- Structural Biology
Background:
- The 106th Boehringer Ingelheim Fonds International Titisee Conference convened in October 2012.
- The conference focused on the principles of chromosome assembly and organization.
Framework:
- Biologists, chemists, and physicists collaborated to discuss chromatin.
- Topics spanned static structural insights to dynamic cellular processes.
Implementation:
- Discussions integrated data from crystal structures.
- Analyses of chromatin dynamics within living cells were presented.
Implications:
- This multidisciplinary approach advanced the understanding of chromatin self-assembly and self-organization.
- The conference highlighted the interplay between static structures and dynamic cellular functions in chromatin biology.

02:11Forces Acting on Chromosomes
During mitosis, chromosome movements occur through the interplay of multiple piconewton level forces. In prometaphase, these forces help in chromosome assembly or congression at the equatorial plane, eventually leading to their alignment at the metaphase plate. The forces acting on the chromosomes are space and time-dependent; therefore, they vary with the position of the chromosomes as the cell progresses through mitosis.

02:21Chromatin Packaging
Each human somatic cell contains 6 billion base-pairs of DNA. Each base-pair is 0.34 nm long, which means that each diploid cell contains a staggering 2 meters of DNA. How is such a long DNA strand packed inside a nucleus measuring only 10 - 20 microns in diameter?
The chromatin
In combination with specialized DNA binding protein called Histones, the DNA double helix forms a compact DNA: protein complex called chromatin. The chromatin itself is further compacted into higher-order structures.

02:35Chromatin Position Affects Gene Expression
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.
