2008;3(3):327-336. Phenotypic variability may be striking. [12] Females with such mutations may be completely normal or have clinical features ranging from mild learning disabilities, to Angelman ...

The map also identifies areas of DNA that are devoid of major reshuffling, likely to protect critical genetic functions or prevent chromosomal ... can contribute to mutations passed to offspring.

this new genetic analysis looked at the chromosomal level, the genome level, and even the nucleotides of the Chernobyl dogs, and found no abnormalities indicative of radiation-induced mutation.

Mutations in the oncogenes may cause a cell to grow and divide too quickly. When this occurs, it may multiply at an out-of-control rate and develop into cancer. Chromosomes are threadlike ...
