what strand of DNA the Laurence-moon syndrome affect?
594366
laurence-moon-bardet-biedl syndrome (lmbbs) is an autosomal recessive genetic disorder characterized by obesity, retinal degeneration, extra digits on the hands and feet, and intellectual impairment. \n\n<since the dna is distributed into chromosomes, the specific dna strands you're looking for would be the chromosomal location of the genes responsible for the syndrome so...>\n\nin 1993, the gene responsible for lmbss was located on chromosome 16q21 (type 2). shortly thereafter, another gene on chromosome 11q13 (type 1) was identified. since then, two others were found on chromosomes 3p12 (type 3) and 15q22 (type 4). the most common form of lmbb is type 1 and the most rare form is type 3. it is expected, however, that another gene that causes the syndrome also exists because there are identified cases that have none of these four defects.\n\nthe disorder laurence-moon-bardet-biedl syndrome (lmbbs) was recently split into laurence-moon (lms) and bardet-biedl (bbs), where lms is characterized as the cases involving mental retardation and spastic paresis and bbs involved obesity, polydactyly, and learning disabilities. it has been shown that bbs represents the majority of published cases.

*Shaking my shaggy skull* Sadly no as it is a chromosomal disorder, modern science has not advanced that far.\n:c(\nWolf-Hirschhorn syndrome is an extremely rare chromosomal disorder caused by a partial deletion (monosomy) of the short arm ("p") of chromosome 4. Major symptoms may include extremely wide-set eyes (ocular hypertelorism) with a broad or beaked nose, a small head (microcephaly), low-set malformed ears, mental and growth deficiency, heart (cardiac) defects, and seizures. Because the amount of genetic material deleted varies, the symptoms of this syndrome vary from case to case.\nTreatment is cosmetic mostly in nature. Treatment of Wolf-Hirschhorn Syndrome may include surgical repair of malformations. For example, surgery may be performed to correct cleft lip and palate. Other treatment is symptomatic and supportive. A team approach may be helpful in ensuring that affected individuals reach their fullest potential. Such a team approach may include special remedial education, physical therapy, and other medical, social, or vocational services. Genetic counseling will also be of benefit for families of children with Wolf-Hirschhorn Syndrome.\nIn the future with the advance of genetic sciences perhaps we can find cures that will do things like repair DNA and chromosomal disorders. http://www.hhm.k12.nf.ca/parsonsbio/bioproject/cure.html\nStem Cell research was making interesting progress along those lines until recently.\nThere are currently 26 labs in the US alone studying WHS\nSome resource links are as follows\nhttp://www.madisonsfoundation.org/content/3/1/display.asp?did=230\nhttp://www.webmd.com/hw/raising_a_family/nord622.asp\nhttp://hw.healthdialog.com/kbase/nord/nord622.htm\nhttp://www.rarediseases.org/search/rdbdetail_abstract.html?disname=Wolf+Hirschhorn+Syndrome#\nhttp://www.hhm.k12.nf.ca/parsonsbio/bioproject/WolfHome.html

The DNA which carries genetic information in cells is normally packaged in the form of one or more large macromolecules called chromosomes.\n\nA chromosome, from the Greek χρώμα (color) and σώμα (body) is, minimally, a very long, continuous piece of DNA (a single DNA molecule), which contains many genes, regulatory elements and other intervening nucleotide sequences.

DNA = deriboneucleic acid\nRNA = riboneuclic acid\nRNA is present in each human cell in the lipoprotein (outside the cell) part. \nDNA is present in the neucleus of the cell. to be more specific, in the chromosomes inside the neucleus of the cell. so, it is only the DNA that carries the genetic property to the offsprings.\n\nas for your project, you can surely include it as a chapter.however make it sure that it is not too lengthy to dominate the main subject.\nyou can also include a chapter related to "clones and cloning". that could help you in showing it more clearly that its only the DNA that helps to transfer the genetic property to the young ones.\nif you need any further help in your project, you can contact me at \n\nmangeshome1982@yahoo.co.in\n\ngood luck.

In a short & crude way, DNA seems to have the information that drive life in and around us. ‘If I can’ read this molecule, I can perhaps tell the possibilities of me or my child being susceptible to a disease. \n\nGenetics is about knowing:\nhow exactly the DNA is linked to life and, more importantly, \nhow is the information in DNA is passed through generations. Genetics also explains a lot about evolution-theories.\n\nThese subjects fascinate many of us as we have intriguing questions about life.\n\nWhy is it important to know about these for a non-biologist? Doctor J is correct. Just wanted to elaborate on this. \n\nIf DNA has information about different forms of life, modifying the DNA can be a potential way to identify and/or cure some of the diseases, or obtain better crop, etc. But since modifying DNA can have so many different implications, including the hereditary and evolutionary aspects of the future generations of life forms on earth, the current generation may have lot of responsibilities. Our policy makers, politicians, media and the rest of us can contribute by our awareness of DNA, cells, genetics etc. \n\nThere can be uncertainty about the future possibilities/effects due to genetic changes that are induced by us, the human beings. We still don’t know many things; like, how to read the complete DNA (genome). Hence, there is a space for interpretation of future effects of genetic engineering. It is hard to completely rule out the possible negative effects. But the benefits, when they really exist, can be tremendous. Restraint and good regulations are very crucial. We can, and perhaps, should influence the policy makers by our awareness.

Deoxyribonucleic acid (DNA) is a nucleic acid —usually in the form of a double helix— that contains the genetic instructions specifying the biological development of all cellular forms of life, and most viruses. DNA is a long polymer of nucleotides (a polynucleotide) and encodes the sequence of the amino acid residues in proteins using the genetic code, a triplet code of nucleotides.\n\nIn complex eukaryotic cells such as those from plants, animals, fungi and protists, most of the DNA is located in the cell nucleus. By contrast, in simpler cells called prokaryotes, including the eubacteria and archaea, DNA is not separated from the cytoplasm by a nuclear envelope. The cellular organelles known as chloroplasts and mitochondria also carry DNA.\n\nDNA is often referred to as the molecule of heredity as it is responsible for the genetic propagation of most inherited traits. In humans, these traits can range from hair colour to disease susceptibility. During cell division, DNA is replicated and can be transmitted to offspring during reproduction. Lineage studies can be done based on the facts that the mitochondrial DNA only comes from the mother, and the male Y chromosome only comes from the father.\n\nEvery person's DNA, their genome, is inherited from both parents. The mother's mitochondrial DNA together with twenty-three chromosomes from each parent combine to form the genome of a zygote, the fertilized egg. As a result, with certain exceptions such as red blood cells, most human cells contain 23 pairs of chromosomes, together with mitochondrial DNA inherited from the mother.

A chromosome, cosisting of a strands of DNA, or Deoxy ribose nucleic acid, is composed of a double sided chain of proteins known as nucleic acids. These acids, Adenine, Guanine, Cytosine and Thiamine may bond with any other nucleic acid in the ribs of the "ladder" of the DNA strand, but can only bond in certain pairs to form the "steps" of the ladder. Guanine only bonds to Cytosine, and Thiamine only bonds to Adenine. In the RNA molecule, which consists of only one "rung" of the "ladder", Thiamine is replaced by Uracil. Sets of these nucleic acids are what determines the traits expressed, "phenotypically", in the organism.

Inside of each cell of the human body is a nucleus.  Inside of it are genes and chromosomes.  Inside of those are complex strands of proteins and amino acids that together are calle deoxyribonucleic acid or DNA.  This DNA contains the "blueprint" for an entire human being.  When two people mate, their DNA gets combined to form a new human, unique but having many characteristics shared by the parents' DNA.  Have you ever heard the term "genetic lottery"?  This is because each time the DNA from two humans is combined to make a third new human, the combination of DNA is to an extent random.  Only to an extent.  I inherited my mother's bad vision and my father's bad teeth.  I inherited my father's nose.  But I am taller than either of my parents.  My hair is a completely different color than either of theirs.  Sometimes DNA, genes, and chromosomes are imperfectly formed.  Each gene controls certain characteristics about a human being.  Completely normal parents can wind up having a baby with Downs' Syndrome (Mongolism, a type of mental and physical retardation).  Completely normal parents can wind up having a dwarf baby.  But other problems are passed down directly from one generation to the next.  Hemophilia is one example, the people whose blood won't clot.  They can bleed to death from a cut.  If they fall they can bleed internally until they die.  Hemophilia is passed down from one generations to the next in the female line.  Queen Victoria, who was related to most of the people of the royal and imperial houses of pre-World War One Europe, was a carrier of the genetic defect of hemophilia.  The women who carry this are usually immune to it.  It is the boys they give birth to that can suffer and die from uninterrupted bleeding due to this genetic defect.  How to prevent one's son from being hemophiliac if one is a female carrier?  Adopt.

Not that I'm aware of. This genetic condition involves the X and Y chromosomes, and not anything else.

It affects us at the DNA level by increasing the level of mutations.  These mutations can cause abnormal growths, cancerous cells, & other unpleasant things.\n\nHowever it is possible that some of these mutations could be benificial.
