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.

The Y chromosome has traditionally been associated with male sex-specific traits, since it contains genes like SRY – the switch that pushes a developing embryo down the path of male sexual ...

Insights from fully sequencing 43 human Y chromosomes Date: August 23, 2023 Source: Jackson Laboratory Summary: Highly challenging to sequence and long overlooked, the human Y chromosome's ...

The human Y chromosome, responsible for determining male sex, finally has gotten an end-to-end examination. The Y chromosome is the smallest of the human chromosomes. “In the old time, people ...

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.

The first HACs were developed 25 years ago, and artificial chromosome technology is already well advanced for the smaller, simpler chromosomes of lower organisms such as bacteria and yeast. Human ...

For many years, the human Y chromosome was terra incognita. Scientists completed the genetic sequences of other chromosomes, the threadlike structures that hold an organism’s DNA.

What was once the final frontier of the human genome -- the Y chromosome -- has just been mapped out in its entirety. Scientists used advanced sequencing technologies to read out the full DNA ...
