Cri Du Chat Syndrome Introduction Cri du chat syndrome also known as 5p syndrome and cat cry syndrome - is a rare genetic condition that is caused by the deletion (a missing piece) of genetic material on the small arm of chromosome 5. Cri du Chat is a genetic disorder first described and named in 1963 by Jerome Lejeune. Cri-du-Chat means "cat’s cry" in French. The disorder causes the baby to produce a high pitched and cat like cry because of the structural abnormality and low

General Biology In Class Quiz - Chapter 5 10 points 1. Explain the difference between chromatin‚ chromosome‚ nucleosome and histones. Chromatin- is the combination of DNA‚ histone‚ and other proteins that make up chromosomes. Chromosome- is minimally very long continuous piece of DNA which contains many genes regulatory elements and other intervening nucleotide sequences. Nucleosome- is considered to be one of the most stable particles in the DNA that helps in the compacting and transcripting

replicating its DNA. After the DNA is replicated‚ the chromosomes line up in the middle of the cell where each pair touches each other and genetic information from the alleles are shuffled and exchanged‚ a process called crossing-over. The crossing-over over of chromosomes results in what is called recombination‚ where genetic information from the maternal chromosome (chromosome from the mother) is now on the paternal chromosome (chromosome from the father) or vice versa. Crossing-over and recombination

Mitosis is a cellular process that replicates chromosomes and produces two identical nuclei in preparation for cell division‚ from the original cell two cells are derived‚ each of which possesses the same genetic material. Mitosis has five phases: interphase‚ prophase‚ metaphase‚ anaphase and telophase. Interphase The DNA duplicates during interphase to prepare for mitosis. Chromosomes are not clearly discerned in the nucleus. Prophase Chromatin in the nucleus begins to condense and becomes visible

that occur in a regular recognizable pattern are referred to as syndromes--for example‚ the FETAL ALCOHOL SYNDROME sometimes observed in infants of mothers who drank heavily when pregnant. Birth defects may result from the action of genes‚ chromosomes‚ or the environment on the developing fetus‚ but often the cause cannot be determined. Inherited Defects Abnormal genes cause a significant number of different birth defects. Some can be identified as a single-gene disorder that is inherited

Cri du Chat Syndrome goes by many different names including: 5p deletion syndrome‚ 5p- syndrome‚ cat cry syndrome‚ chromosome 5p- syndrome‚ and monosomy 5p. Deletion of part of a chromosome causes Cri du Chat Syndrome. An affected person does not have a portion of the short end of the fifth chromosome‚ also know as the 5p- chromosome section. The larger the section of the chromosome that is missing‚ that is to say the more important deleted genes‚ the more severe the physical and mental symptoms

Results RAPD and ISSR fingerprint In order to evaluate the efficiency of RAPD-PCR fingerprinting for Cajanus cajan L. cultivar‚ the DNA was used as templates for 7 RAPD primers banding modality. Total number of magnified fragments in the Cajanus cajan L. cultivar value of each primer was represented in Table 2. Total of 26 bands were obtained for all primers. The highest band number was produced with primer OP-A5 and OP-B4‚ while the lowest band number was created with primer OP-A13. The RAPD banding
