study was to fingerprinting the Cajanus cajan plant ‚ then extract the flavonoids fraction (FFCC) with methanol extract‚ and assess the antimutagenic efficacy of the fraction extract to reduce genotoxicity induced by cyclophosphamide (CP) using chromosome aberrations‚ in mice bone-marrow cells and spermatocytes‚ and DNA damage by comet assay. Three doses from FFCC were orally administrated once for 24h at 50‚ 100 and 200 mg/kg b.wt simultaneously with CP at 20 mg/kg b.wt. The results revealed that

Edwards Syndrome‚ also known as Trisomy 18‚ is a genetic syndrome of severe to profound mental retardation. It is caused by the presence of an extra chromosome 18 in some or all of the cells in the body. Babies with this condition typically do not survive but for a few months after birth. About sixty percent of newborns with this condition die within the first week‚ and eighty percent do not survive through the first month

1. Name the condition. Edwards Syndrome (or Trisomy 18) 2. Outline the chromosomal abnormality. Trisomy 18‚ or Edwards syndrome‚ occurs when a person has a third copy of material from chromosome 18 instead of the usual two copies. 3. What chromosomes are involved? Chromosome 18 is the only chromosome involved with this disorder. 4. What does it affect? The majority of children born with Edward ’s syndrome appear both fragile and weak; many are underweight. Their heads are unusually

within the same family. There are two forms of Opitz G/BBB syndrome‚ which are distinguished by their genetic causes and patterns of inheritance. The X-linked form of Opitz G/BBB syndrome is caused by a mutation in a specific gene‚ MID1‚ on the X chromosome. Autosomal dominant Opitz G/BBB syndrome is caused by a mutation in an as-yet unidentified gene

2233 Heredity Paper Assignment CRI-DU-CHAT SYNDROME (CDCS) Cri-du-chat syndrome (CDCS) refers to a unique combination of physical and mental characteristics associated with a loss of genetic material on the distal short arm of the fifth chromosome. This loss of genetic material is referred to as a deletion. CDCS is also called 5p- syndrome (5p-S)‚ 5p monosomy‚ or Cat Cry syndrome which was first identified by Dr. Jerome Lejeune in 1963. He named so because of the distinctive cry in infancy

the gene on chromosome 5‚ which affects facial development. About 40 percent of the time‚ one parent has the Treacher Collins Syndrome gene. Geneticists can now determine whether the Treacher Collins gene is a new mutation or one that has been passed on. There are new studies being done to see about the possibilities of there being other genes that could be involved with this syndrome. Treacher Collins Syndrome is believed to be caused by a change in the TCOF1 gene on chromosome 5‚ which affects
