How chromosomes change their shape during cell differentiation

The human genome is made up of 46 chromosomes, each of which has a length of about 100 to 200 million base pairs, the building blocks of the DNA double helix. Even during interphase, the period in between the cell division ...

Detailed map shows how viruses infect humans

Biologists at Columbia University Vagelos College of Physicians and Surgeons have leveraged a computational method to map protein-protein interactions between all known human-infecting viruses and the cells they infect. The ...

New progress in developing an animal model of hepatitis C

Small differences in a liver cell protein have significant impacts on hepatitis C virus replication in mice and humans, findings that could facilitate the development of a mouse model of the infection. The report, led by ...

Frog eggs help researchers understand repair of DNA damages

The DNA replication process in which cells divide to create new cells also triggers repair of DNA damage, researchers from the University of Copenhagen report in a new study. The researchers studied extracts from frog eggs, ...

Researchers unravel mystery of how, when DNA replicates

A team of Florida State University researchers has unlocked a decades-old mystery about how a critical cellular process is regulated and what that could mean for the future study of genetics.
