gene

In a new study, the international collaborators analyzed the genomes of more than 48,000 individual breast cells from women without cancer, using novel techniques for decoding the genes of single cells.

Previous studies have identified specific genes in these regions that also are associated with breast cancer, according to Navin.

All cells within an organism contain the same genes, but which genes are expressed at any given time is what determines each cell's identity and function.

These DNAm changes can turn genes on or off without changing the DNA code.

"Each gene was like a single word. However, there was a piece of critical information lacking: transcription initiation sites for individual genes."
