Bentyl is a prescription drug licensed to treat irritable bowel syndrome (IBS). By blocking specific receptors in the smooth muscles of the digestive tract, the medication can help relieve the painful spasms associated with IBS.
When ionizing radiation causes DNA damage (mutations) in male or female reproductive (ggerm h) cells, that damage can be transmitted to the next generation (F 1).This is in contrast to mutations in somatic cells, which are not transmitted. Detection of human germ cell mutations is difficult, especially at low doses.hen ionizing radiation causes DNA damage (mutations) in male or female reproductive (ggerm h) cells, that damage can be transmitted to the next generation (F 1).
A mutation is a change in the base sequence of DNA that can affect the structure and function of proteins when they occur within a gene. Mutations can be spontaneously caused by copying errors during DNA replication or induced by exposure to external elements such as chemical mutagens, radiation or viruses. Cystic fibrosis is an example of a disease which can result from a nonsense mutation (this may not be the only cause though). 2  Frameshift mutations occur when the addition or removal of a base alters the reading frame of the gene.
