Cigarette smoke causes breaks in DNA and defects to a cell's chromosomes, Pitt study finds
...eaks are considered the most mutagenic type of DNA damage
because the broken ends can fuse to other chromosomes in the cell. Chromosome fusion is detrimental to normal chromosome segregation, which in turn leads to genetic imbalances," explained Dr. Saunders, associate professor of biological sciences, Univ...

Enzyme maintaining chromosome ends is linked to bone cancer recurrence, decreased survival
.... These telomeres protect the chromosome ends from damage
that otherwise would trigger apoptosis--the cell's self-destruct program. Most cancers activate telomerase to maintain telomeres in order to protect their chromosomes and ensure the cells survive and multiply. However, a minority of cancers use a p...
