Repetitive DNA and the D1 protein help matching fruit fly chromosomes recognize one another before eggs form.

Inside each human cell, about 2 meters (6.6 feet) of genomic DNA must be accurately copied and equally transmitted to two ...

A long-running DNA mystery linked to cancer and chromosome behavior may finally have been cracked. The breakthrough, ...

For years, the dense loops of repetitive DNA clustered near the middle of chromosomes were treated as evolutionary clutter. According to the new study published in Nature, titled 'Meiotic pairing ...

Today, it is common knowledge in biology textbooks that "genes are made of DNA and are lined up on chromosomes."However, more ...

Sexual reproduction usually reshuffles genetic information, creating offspring that differ from their parents. But one small ...

A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

The body cells of humans and animals contain a double set of chromosomes. One half of the genetic material comes from the mother, the other stems from the father. During the formation of sperm or egg ...

The body cells of humans and animals contain a double set of chromosomes. One half of the genetic material comes from the mother, the other stems from the father. During the formation of sperm or egg ...

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 ...

Every cell that produces eggs or sperm must first sort its chromosomes into matching pairs, lining up each one with its homologous partner before they exchange genetic material. According to the ...
