Each nucleosome is made of DNA wrapped around eight histone proteins ... where additional H1 histone proteins are associated with each nucleosome to maintain the chromosome structure.

How is all of that DNA packaged so tightly into chromosomes and squeezed into ... which contains eight histone proteins and about 146 base pairs of DNA (Van Holde, 1988; Wolffe, 1999).

The centromere of chromosomes plays a crucial role in cell division. Using the model plant Arabidopsis thaliana, an international team of researchers has investigated how two crucial proteins -- KNL2 ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA ...

This coiling causes the chromosome to resemble a spring. Chromatin refers to proteins that help organize the long DNA molecule. The protein shown here supports and organizes small loops of DNA.

Researchers unveil histone-based age predictors, offering a new window into epigenetic aging and its shared patterns across ...

A single strand of DNA forms a chromosome, like the one displayed to the left. This chromosome is magnified (1000x). That's not nearly enough to show a single strand of DNA, which is only wide ...

Type II DNA topoisomerases (Topo II ... requires the action of condensin proteins and post-translational modifications of histone proteins. In meiotic prophase I, chromosome compaction is further ...

We are interested in the mechanism of chromosome replication ... and monitor accurate genome replication we employ a fully reconstituted DNA replication system based on purified proteins from the ...

The two proteins, KNL2 and CENP-C, are crucial for correctly separating chromosomes during cell division. They dock precisely onto the centromeric DNA, analogous to the "lock and key principle." ...
