Repetitive elements make up over 50% of the human genome. Recent advances in long-read sequencing experimental approaches and data analysis algorithms have made it possible to characterize these ...

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 ...

Kansas City, MO—September 24, 2025—Open a high school biology textbook, and you’ll see human chromosomes lined up two by two, like socks in a drawer. But in about one out of every 800 people, two ...

New research predicts the location of DNA sequences that can form structures besides the canonical double helix — non-B DNA — in the recently released telomere-to-telomere genomes of the great apes, ...

Small plastic or metal bits at the end of shoelaces, known as aglets, prevent laces from unraveling and protect them from wear and tear. Similarly, chromosomes are capped by telomeres—specialized ...

In a study published in Genome Research, a team of researchers, including Cornell College Assistant Professor of Biology Sophie Gillett, looked at regions of human genetic code that are known for ...

A new international study suggests that ancient viral DNA embedded in our genome, which were long dismissed as genetic "junk", may actually play powerful roles in regulating gene expression. Focusing ...
