a question about dna?
100049
Okay i never heard of the law of DNA but to answer the question.  If the condition of hair, straght or curly, is defined by a single gene, than there are two types.  The is a straight gene and a curly gene.  So everyone has two copies of the gene.  One from mom and one from dad.  So if mom gives a curly gene, and dad gives straight, which one will it be?  Well that is described by the law of domninance.  One gene will be stronger than the other.  One allele will out shine the other.  So you need to find out, which gene is dominant and which is recessive.  thats your answer

dna and genetic coding of chromosomes.

I think analyzing the information in DNA has come along way.  This information can be useful for numerous advances in medicine, one being determining ones predisposition of developing certain diseases.  This analysis can take quite a long time but researches are currently working on ways to speed this up, hopefully to less than 1 day.  You can see this article in New Scientist for a further information.  http://www.newscientist.com/article.ns?id=dn9001&feedId=online-news_rss20

It's not expected to be the same. \n\nIn double stranded DNA, A=T and C=G, therefore (A+C)/(G+T) = 1 always. The number of A is not necessarily equal as C. Therefore, (A+T)/(C+G) can be any number, different than 1.

NO. DNA can only be used to identify a person or being, or link to two persons/beings together. It can not PROVE a crime was committed.

DNA has already been cloned, so your question is meaningless. This was done in bacteria over 40 years ago, and is how human insulin is now produced en masse.

Well, at least you don’t want to know a lot! We have split your questions into four separate parts (look for the other questions in our archived list). The first question will be answered here. \n\nWho discovered DNA? \n\nThis is a tough question because it is hard to know what people mean by DNA. Do they mean genes, or the substance DNA or chromosomes or the structure of DNA or… \n\nHere is a brief timeline of some discoveries about DNA: \n\n1856-1865 Gregor Mendel founds genetics. \n\n1869 Johann Friedrich Miescher discovers a weakly acidic substance in human nuclei he calls nuclein. It is later \ncalled DNA. \n\n1882 Walther Fleming discovers chromosomes. \n\n1902-1903 Walter Stanborough Sutton uses grasshoppers to discover that chromosomes have genes. \n\n1924 Chromosomes are shown to be made of protein and DNA. \n\n1928 Franklin Griffith figures out that genetic information can be transferred from heat-killed bacteria to live ones. \n\n1944 Oswald Avery figures out that Griffith’s substance was DNA. \n\n1949 Edwin Chargaff figures out that no matter the species, the amount of adenine (A) equals the amount of thymine (T) and the amount of guanine (G) equals the amount of cytosine (C). \n\n1953 Francis Crick, James Watson and Rosalind Franklin discover the double helix structure of DNA. \n\n1961 Francis Crick and Sidney Bremmer figure out that three bases (a codon) are needed to code for an amino acid \n\n\nSMILE

According to the watson and crick model the DNA\nStucture is built like a spiral staircase .\nFr the rest of it try th link below.

DNA is an acronym for deoxyribonucleic acid, a nucleic acid. Nucleic acid is a substance in the nucleus of a cell. The nucleus is part of the cell separated from the rest of the cell by a membrane. DNA can be found in the cells of all organisms. This includes animals, plants, and all other living things. DNA contains the genetic code of the organism. This code is based on the code from that organism's parents. DNA also helps in protein synthesis.\n\nDNA is shaped like a double helix, which is like a ladder twisted into a spiral. Each "leg" of the "ladder" is a line of nucleotides. A nucleotide is a molecule made of ribose (a 5 carbon sugar), a phosphate group, (which is made of phosphorus and oxygen), and a Nitrogen base. Each nucleotide has one of four kinds of bases.\n\nadenine (A) \nthymine (T) \ncytosine (C) \nguanine (G) \n\nA gene is made of DNA.  Bacteria and viruses have DNA too.  The DNA molecule is shaped like a twisted ladder.  A half DNA ladder is a template for copying the whole. RNA is an intermediary between DNA and protein.    gene is a discrete sequence of DNA nucleotides.A chromosome is a package for DNA.   Some DNA does not encode protein.  Some DNA can jump.    DNA responds to signals from outside the cell.    DNA is only the starting point for understanding human biology.\nVR

dna of any person is as unique as the stripes on tiger skin.....so theres no ques to get confused.....and dna is present in the neucleus of cell of a person and the thing is that the nucleus is absent in blood cell so there s no fear of anykind that dna will change or sumthing else .....clear that theres no nucleus in blood cell n dna is present in nucleus only

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.

Checkout what is being done with nanotechnology and building structures, Complex structures!, with dna strands!\n\nhttp://www.nature.com/nature/links/040212/040212-1.html\n\nIf it CAN and it can be measured imagine what can be done!\nalmost scary!

B) RNA is found only inside the nucleus, whereas DNA is found only outside the nucleus.\n\nIn order for the statement to be true, the subjects (RNA & DNA) should be switched.

There is about a 1 in 10 billion chance that someone would have the same dna as you, unless you have an identical twin.  Scienctists don't like to say "never", but that's really close.

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