How does DNA can contain all the information about your genetics...?

Your body is made up of proteins. Fats and sugars are used to fuel your body. You eat them, and whatever you eat that is not a sugar or a fat can be transformed into one by your body. Usually, proteins are broken into its constituents amino acids and those are used to build new proteins.\n\nThen there are RNA molecules, which act as blueprints for your proteins. Each RNA contains the orders to create a certain protein (translation). Among these proteins are enzymes, that are proteins useful to create other proteins.\n\nIn turn, all these RNA molecules are created from your DNA (transcription). DNA is a very long molecule, and from segments of it the short RNA molecules can be created.\n\nSo DNA contains the information to make all the structural proteins in your body, and to make the enzymes that help build those proteins and that help put them in the right places.\n\nEach cell in your body has a copy of your complete DNA. That tells the cell what proteins to produce, where to put them, and what sort of production to emphasize for that particular cell.\n\nSo cells in the hair follicles are 'programmed' to produce hairs, while neurons are 'programmed' to produce electrical impulses and store a memory of them.\n\nHow does each cell know what it is supposed to do?\n\nEarly in development, when you're a zygote, your cells are not differentiated. Any cell can become any part of your body. Then, as they divide, their position in the ball of cells formed generates certain signals that activate or deactivate certain parts of the DNA.\n\nThe long DNA molecule is packed, meaning that some regions are left free to be transcribed (that is, to generate the RNAs that will generate the proteins from there), while others are tightly closed with proteins called histones (generated by the DNA itself, and acting according to the differentiation signal).\n\nThe undifferentiated cells are called "stem cells" and with the right signals can be turned into almost anything, from an eye cell to a neuron or a kidney cell. Once they become differentiated, they assume their role for themselves and all their descendants.\n\nDifferentiated cells only translate the relevant parts of their genetic code. In fact, all cells contain all the information and could potentially take on the role of any other cell, but that is prevented by the tight histone packing of certain segments of the DNA.\n\nIf a way were found to un-differentiate an already mature cell, whoever does it would become rich (that cell could be used to generate more and generate entire tissues or even organs to replace defective tissues and organs).\n\nI hope it's fairly clear.

you need to speak to a genetics counselor usually located at a medical university hospital\nthen you would need a family history, then finally a sanple of tissue for the dna to be read of each but thats not needed once a genetics counsel takes place

dna is a chemical code inside every living cell that determines how the cell functions.
203875
Usually described as about 2 meters for all of the dna in one human cell.  This actually consists of many separate strands of dna.

The length of hair and all other aspects of cell growth and type of cell is based on DNA.\n\nDNA is the code of life. It also determines the specific characteristic of your family traits through Chromosomes passed on by your parents.

chromosomes from different parents determine the genetic structure of the child - with recessive genes only becoming apaprent if they are present from both parents

youve got promoters, enhancers, introns and exons, insulators, terminators..is that what you were asking?

In many cases the so-called 'junk' DNA carried by many organisms is probably similar to the old wives' tale that we only use 10% of our brains.\n\nIt looks like a lot of DNA goes unused in the day to day operations of the cell and in the process of gene transcription, but this probably means we just don't know yet what it does, and not that it isn't needed.\n\nEverytime medical science has said that some organ or other is vestigial and serves no purpose, we soon find out that it really does have a function.  Not always a major role, or a vital function, but some function.  Usually this occurs sometime after the doctors have spent decades performing needless operations removing tonsils or appendixes willy nilly.\n\nIt seems likely that someday we'll find that a lot of that DNA really does serve a purpose.  Perhaps it is only switched on in special circumstances, or maybe it's something like a glossary that reminds the cell how the stuff in the rest of the DNA is supposed to be spelled, so that random errors can be corrected (or added to).  \n\nMaybe it really is useless, ancient data.  The genetic equivalent of our high school yearbooks or the address book from twenty years ago that's still stuck in the back of one desk drawer.  \n\nPerhaps it's material that the cell isn't using right now, but would be really valuable if we did.  Maybe it's like that cardboard box that goes through six moves without being opened, and so we finally open it, and HEY, COOL!!! LEGO!!!!

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 and encodes the sequence of the amino acid residues in proteins using the genetic code, a triplet code of nucleotides\n\nhttp://en.wikipedia.org/wiki/Dna

It is important to understand that, with more than one billion molecules and 1/3 (333+ million) of those being the programming molecules, there are more than 122.9637 x 10 to the 32nd power (sorry, I don't have super script on this software) possible different combinations in just one chromosome. That is 1,229,637 with 28 zeros behind it. Now multiply that times the 46 chromosomes you have in every cell in your body. It is easy to see how complex this can get.\n\nSo now the 3% and yes it is 3, becomes very big.\nAlso note not all of DNA is functional.

DNA can trace a long ways back. There are "markers" that persons of the same relation will carrying. one set of markers is for your mothers side and another from your fathers side. if i rememeber right the mothers side is a little eaiser to trace back. :)

Short answer:\n\nYour genes are a combination of both of your parents genes, and they constitute a full set.  Through meiosis however, a process which creates sperm and egg cells, the cells divide in such a way as to halve their genetic "info".  These halves are carried by the sperm and egg cells, and recombined into a single, new whole through fertilization.

DNA is used to create many different kinds of protiens.  It is the template that your body uses to create them.

DNA is an abbreviation for Deoxyribonucleic Acid. \n A piece of a chromosome that dictates a particular trait is called a gene. \n Each DNA strand is 10 atoms wide. \n The DNA stands in your body stretched out would be about 500 million miles long. \n There are so many millions of base pairs in each person's DNA that every person has a different sequence

deoxyribonucleic acid-but you dont really need to know that

Simply DNA is an organic computer program which contains all of the information to grow an organic creature, such as mice, worms and humans.\n\nDNA is all but as individual as you are, so DNA can be used by forensic scientists to narrow down the search for the perp in a murder enquiry.\n\nDNA (if read) can provide much information:\n\napproximate height, hair colour, ethnicity, eye colour, approximate age, etc...
