Depending on the setting, the ability of a crucial bacterium in biotechnology—Agrobacterium tumefaciens—to transfer its DNA ...

Researchers for the first time have successfully fused two chromosomes in mice and shown that the new karyotype can be transmitted to offspring. The researchers used a strategy that involved haploid ...

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 ...

Researchers have discovered how the MSL complex responsible for dosage compensation can distinguish the X chromosome from autosomes in flies. A lab used a unique research approach to determine the ...

The sex we're assigned at birth depends largely on a genetic flip of the coin: X or Y? Two X chromosomes and you (almost always) develop ovaries. An X and a Y chromosome? Testes. These packages of ...
