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 ...

which occurs in a large circular segment of DNA that exists outside of any chromosome. Although glyphosate resistance had been linked to this odd structure previously, the study provided new insights ...

Small sections of the chromosome, called genes, code for the RNA and protein molecules required by an organism. In some organisms, like humans, chromosomes are linear, but in other organisms ...

"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 ...

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 ...

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 ...

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 ...

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 ...
