Chromosomes are a highly condensed form of DNA and are crucial for cell division. During mitosis, chromosomes ensure that genetic material is equally divided among the daughter cells. Interestingly, ...

Healthy cells work hard to maintain the integrity of our DNA, but occasionally, a chromosome can get separated from the others and break apart during cell division. The tiny fragments of DNA then get ...

Researchers have solved a long-standing mystery of how abnormal chromosomes drive cancer, identifying 81 new genes involved in aggressive breast cancer. The discovery expands understanding of the ...

Translocations, in genetics, happen when chromosomes break and the pieces attach to other chromosomes. This mixing of genetic material has important results. The resultant chromosomes are lacking in ...

Stefan Fröhling, M.D., and Hartmut Döhner, M.D. The cause of chromosomal abnormalities remains poorly understood. Studies of various types of leukemia have shown that certain environmental and ...

Human egg cells are often prone to chromosomal errors. As women age, the error rate increases sharply — and can contribute to infertility, pregnancy loss, and ...

A new prenatal test developed by researchers at Columbia University Fertility Center can determine if a fetus or embryo has the right number of chromosomes at a fraction of the time and cost of ...

Researchers have solved a long-standing mystery of how abnormal chromosomes drive cancer, identifying 81 new genes involved ...

When a species lives in two distinct types of habitats, individuals with traits better suited to each habitat will thrive and reproduce, naturally selecting descendants with those traits. But what ...
