Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate proportions and for cells to function correctly. When errors occur during ...

AMES, Iowa – A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, ...

Researchers have made a significant advancement toward understanding how the human genome is organized inside a single cell. This knowledge is crucial for analyzing how DNA structure influences gene ...

The complete assembly of each human chromosome is essential for understanding human biology and evolution. Using complementary long-read sequencing technologies, we complete the first linear assembly ...

Two new studies of the evolutionary history of the Y chromosome show that, contrary to popular (if not scientific) belief, the male is not at risk of dying out. The Y chromosome which, among other ...

The Stowers Institute's Workman Lab has shed new light on a novel histone acetyltransferase protein complex called ATAC. Acetyltransferases are enzymes that introduce a new acetyl functional group ...

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 ...

Three specific genes on chromosome 21 drive widespread brain changes in Down syndrome, uncovering a new framework for ...
