The immature egg cells can remain in suspended animation for decades after birth, until they are activated to undergo ovulation. Only then does the process lurch back into motion: The egg cell finally ...

Chromosomes in egg cells within fetal ovaries must be spliced and sorted perfectly. A new landmark study from UC Davis shows how protecting Holliday junctions allows this to happen.

Robertsonian chromosomes (ROB) are a type of structurally variant chromosome that is created when two chromosomes fuse together to form an unusual bond. Found commonly in nature, these chromosomes are ...

A mixture of DNA and proteins—known as "chromatin"—sits inside every cell nucleus as a jumbled puddle of genetic information. As cells prepare to divide during mitosis, the chromatin is condensed into ...

Men who have lost their Y chromosome from a significant number of their immune cells are more likely to have narrow blood vessels, a key contributor to heart disease, according to a study of more than ...

Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

The loss of the Y chromosome in tumour cells is linked to poor outcomes for people with cancer 1, but this genetic alteration might also compromise immune cells that would otherwise fight the disease.

When cancer cells in male patients and immune cells in their tumors both lose the Y chromosome, those patients tend to experience poorer outcomes than patients without Y chromosome loss, according to ...

Women, on average, live longer than men. This trend can be seen as far back as records stretch, and is true of every country in the world today. Many explanations have been put forward: men take more ...
