...es studying an abnormal gene called BCR-ABL, which produces two forms of leukemia -- chronic myelogenous leukemia and acute lymphoblastic leukemia. The BCR-ABL gene forms when a genetic mistake occurs in bone marrow cells destined to become white blood cells.

.... The burning of trees and grasses on land produces charred particles, or charcoal. Charcoal may then be transported long distances by winds and rivers to coastal and ocean environments, where it's then preserved in ocean sediments. Explains Verardo, "Charcoal may be swept aloft in plumes rising fro...Newly Discovered Gene Halts Cell Division and May Have Cancer Link
...D2 gene comes in. The research suggests that MAD2 produces a protein that sits at the centromere of each chromosome and waits for the thread-like fibers to attach. If the fibers attach properly, cell division proceeds and each new cell gets a complete copy of the genetic blueprint of the original cell.
