An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have ...

A DNA molecule can be linear – as in the case of human chromosomes – or circular. Examples of circular DNA molecules include bacterial chromosomes and human mitochondrial DNA.

A human cell carries in its nucleus two meters of spiraling DNA, split up among the 46 slender, double-helical molecules that are its chromosomes. Most of the time, that DNA looks like a tangled ...

There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA ...

Kinetochores prefer the 'silent' DNA sections of the chromosome. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2011 / 07 / 110705122728.htm ...

Each of our 46 chromosomes is composed of double-stranded DNA. During homologous recombination, sections around a double-strand break are cut away, and the ends of the broken DNA molecule invade the ...

The most exciting thing we revealed is the idea that the shape of a DNA molecule can affect its ability to change. In the early 20th century, modernist architecture had the idea that the form of a ...

Although scientists have been able to see single DNA molecules since the early 1960s, we could not tell where in the chromosomes any molecule came from so we could not map anything.

Careful replication and segregation of the DNA molecule, packaged into chromosomes, allows for the accurate inheritance of genetic instructions to each new daughter cell. DNA replication is a ...
