In fact, 33 percent of the residents had undergone chromosomal damage; in a typical population, chromosomal damage affects 1% of people.

They have also been related to chromosomal damage and increased incidence of cervical arch defects as they are capable of cleaving DNA.

With such limited numbers, researchers are loath to say with any certainty that freezing and thawing will not result in chromosomal damage to the delicate egg.

In studies of chromosomal changes in human users and in monkeys, the balance of evidence suggests no increase in chromosomal damage.

Poppy seeds are cancer presenters (blocking 80% of the chromosomal damage in carcinogen).

The children and other test animals developed chromosomal (mutagenic) damage of the blood cells, which has been linked to cancer.

The positive result of induced chromosomal damage is an increase in frequency of micronucelated PCEs.
