This odd arrangement, the authors found, influences the three-dimensional structure of the entire chromosome. “This is definitely a breakthrough within the field. We’ve been generating assemblies for ...

Scientists uncovered how whole-genome duplication emerges and remains stable over thousands of generations of evolution in the lab.

The echidna genome sequence provided here helps researchers trace the genetic events that led to this remarkable chromosomal arrangement. The high-quality sequence with very few gaps presented ...

"We are finding the 3D structure of the genome," said Satoshi Namekawa, professor of microbiology and molecular genetics at the University of California, Davis and senior author on one of the papers.

Each cell of the human body contains two meters of DNA. The whole secret lies in the intricate three-dimensional arrangement that allows DNA strands to be efficiently organized and compacted ...

Indeed, it is possible to reorder these ancestral syntenic fragments into their simplest arrangement, thereby recreating the ancestral genome (Figure 3). In the near future, with the availability ...

Genome and mutations DNA replication is carefully controlled to preserve the genetic information. However, changes in the genome do sometimes occur. These changes are known as mutations.

With the brittle star genome in hand, Marlétaz and his team investigated another important feature of the animal: their ability to regenerate. Like many other echinoderms, brittle stars can regenerate ...

Except for identical twins, each person's DNA is unique. This is why people can be identified using DNA fingerprinting. DNA can be cut up and separated, which can form a 'bar code' that is ...
