The team found that some pancreatic cancer cells gain a major survival edge by carrying copies of critical cancer genes—such ...

"The evolutionary story is that this gene got inserted into a circle at one time and then that circle expanded ... "In the current study, we identified two genes that appear to control maleness on ...

The important thing to realize about linkage is that it helps researchers identify the locations on chromosomes at which specific genes exist. Indeed, linkage is critical for mapping and ...

However, there is some evidence that the Y chromosome is being phased out of the evolutionary pipeline, and could one day disappear altogether — potentially giving rise to a new sex gene in the ...

Bringing the idea full circle, Sutton also concluded ... actually provided strong experimental support that genes were in fact located on chromosomes. The Morgan lab's observations can be simplifi ...

The silencing of the one X chromosome in XX cells is mediated by XIST, a long noncoding RNA that is randomly transcribed from only one X early in development. It coats the DNA and shuts down gene ...

The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

Transposons, or "jumping genes"—DNA segments that can move from one part of the genome to another—are key to bacterial evolution and the development of antibiotic resistance. Cornell ...

"The evolutionary story is that this gene got inserted into a circle at one time and then ... two genes that appear to control maleness on chromosome 3 in Palmer," said lead study author Damilola ...

For one, inserting at the end of the chromosome helps the transposon avoid genes for the cell's core functioning, which reside in the middle of the chromosomes; transposons that can target the ...
