For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...

While all human chromosomes contain repeats, more than 30 million letters of the Y chromosome — out of 62.5 million — are repetitive sequences, sometimes called satellite DNA or junk DNA.

March 31 represents a pivotal moment for the scientific community, as the first “gapless” sequence of the human genome is published. History of the human genome In the 1990s, researchers embarked on a ...

An team of scientists found a family of genome sequences known as “transposable elements.” They play a vital role in gene ...

“Not only can we learn about human evolution from these sequences, but we can apply what we know about their genomes and human genomes to better understand the biology and reproduction of these ...

The newly added sequence, amounting to nearly 10 percent of the human genome, includes some genes and large amounts of repetitive DNA, the trickiest genomic regions to sequence. Most of this DNA ...

The new sequence, which fills in gaps across more than 50% of the Y chromosome’s length, uncovers important genomic features with implications for fertility, such as factors in sperm production.
