Get ready for a biology lesson. Certain plants have extra sets of chromosomes. And it turns out, it's a useful trait for a ...

Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from ...

A new study sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, but the results could help to illuminate an important ...

Sex chromosomes must exchange genetic information at a short region during meiotic cell division. Molecular factors have now been found that alter sex-chromosome structure and enhance this exchange ...

Researchers from the Gerlich Group at IMBA—Institute of Molecular Biotechnology of the Austrian Academy of Sciences—discovered a molecular mechanism that confers special physical properties to ...

Merotelic kinetochore (single kinetochore attaches to microtubules from two spindle poles) has been proposed to be the major mechanism underlying the spontaneous formation of lagging chromosomes, ...

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 ...

The 23 rd chromosome base pair contains what are known as our sex chromosomes. For most females, this pair contains two X chromosomes, while for most males, it contains one X chromosome and one Y ...

A new study led by NYU Langone Health researchers has found that cancer cells are better able to resist treatments when they ...

Imagine a chromosome. You’re probably picturing a nice little X shape, aren’t you? That’s probably what your high school science teacher taught you, anyway. Well, it turns out that’s not actually what ...
