DNA-based vectors = which?
That is:
DNA-based vectors are integrated into the cell's DNA?
Context:
"Our technology does not alter the DNA of the host cells, so completely eliminates the risks associated with DNA-based vectors which can integrate into the cell's DNA and possibly lead to cancer," says Derrick Rossi of the Children's Hospital Boston in Massachusetts, head of the team that developed the new method.
Biological vector = carrier of a disease producing virus
. . ." DNA-based vectors, which can integrate into the cell's DNA and possibly lead to cancer . . "
The "which" refers back to the vector.
@oristarA,
Vector used this way refers to a path or opening. This is saying that they eliminate the possibility of creating a DNA based weakness in the cell making it suseptible to cancer.
