One of the challenges of working with ancient DNA samples is that damage accumulates over time, breaking up the structure of the double helix into ever smaller fragments. In the samples we’ve worked ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Researchers at Rice University are making strides in understanding how chromosome structures change throughout the cell's life cycle. Their study on motorized processes that actively influence the ...

Researchers are making strides in understanding how chromosome structures change throughout the cell's life cycle. Researchers at Rice University are making strides in understanding how chromosome ...

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, they ...

Using chromosome-specific painting, researchers traced how chromosome number changed within the genus Medicago, which ...

Centromeres act as the control centers of chromosomes, ensuring accurate genetic inheritance during cell division, yet they ...

Processes such as wound healing, hair growth, and the continual renewal of cells all rely on cell division. In this process, chromosomes must be evenly distributed between two daughter cells. Even ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA – its genome – and segregate it equally ...

Microscope image of subdermal muscle from a skin of a 52,000-year-old mammoth showing remnants of mammoth nuclei. “We’ve known that tiny fragments of ancient DNA can survive for long periods of time,” ...
