Where is a gene found on DNA?
536642
Maybe you could try to be abit more specific, but genes are information MADE of DNA, so "where" is an odd question to ask... \nMaybe you are referring to the difference between euchromatin (hypomethylated and decondensed) and heterochromatin (highly methylated and condensed) ...? If that´s the case, genes are definitely in euchromatin. That´s why heterochromatin is called "silent" DNA.

It binds to a specific sequence of the gene. If the gene is present, it will bind, if not, it will not bind. Usually the probe also has a fluorescence end, therefore you can use a light to show that it did bind or not.

I don't know how helpful my answer will be, but i will keep it short. The real answer for this question will be in a Biology textbook. \nBasicly, Genes are sequences of chemical pairings in a protein called DNA, found in the Nucleus of all living cells. There are many parts of a gene, each consisting of segments of these pairs of chemicals. When a special protein called a ribosome 'reads' these sequences, it produces other chemicals, proteins and enzymes which regulate your body's functions. \nFor example, There is a gene in your body for the color of your hair. If you are a red-head, your genes code for the release of more red-pigment by your hair follicles. \nThis control can be exerted on anything. Chemicals regulated by genes can stimulate your hypothalmus in your brain, and, for example, make you grow taller, or regulate otehr body functions that affect how you look. \n\nIn your vegetable, a gene might encode for a chemical that prtects it from bacteria or fungus, possibly slowing the decaying process caused by these organisms.

genes, are made up of coded information. It is these codes or mutations of code that contain information that determine your characteristics.

I think you might be refering to plasmids.\nA plasmid is a small circular piece of DNA found in bacteria. A plasmid will often include genes which encode a protein that confers resistance to antibiotics. They can be transferred fromn one bacterium to another and replicate separately from the bacterial genomic DNA. One bacterium can contain many copies of a particular plasmid.\n\nLook it up & see if it is relevant to your enquiry.

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 (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.\n\nThe discovery that DNA was the carrier of genetic information was a process that required many earlier discoveries. The existence of DNA was discovered in the mid 19th century. However, it was only in the early 20th century that researchers began suggesting that it might store genetic information. This gained almost universal acceptance after the structure of DNA was elucidated by James D. Watson and Francis Crick in their 1953 Nature publication. Watson and Crick proposed the central dogma of molecular biology in 1957, describing the process whereby proteins are produced from nucleic DNA. In 1962 Watson, Crick, and Maurice Wilkins jointly received the Nobel Prize for their determination of the structure of DNA.

Restriction enzymes are cutting enzymes found in bacteria. They cut within the DNA molecule and are called restriction endonucleases. They recognize a specific sequence 0f DNA nucleotides and cut the molecules there, producing sticky ends. A missing gene is then added. Another enzyme, DNA ligase, attaches back the DNA molecule. So, of course you end up with two DNA strands. The new DNA produced is known as recombinant DNA. This technology is used in human therapy. Some examples are: human insulin to treat diabetes type I and human factor VIII for the treatment of hemophilia.

This goes to the core of biological and evolutionary theory.\n\nDNA is elements arranged into nucleic acid molecules, arranged in a code (see first link). This code is directly used by a couple of RNA molecules to build protein molecules, ie enzymes (see link two).\n\nProtein molecules make up most of our body structure themselves, but for other parts (made from other molecules - which are combinations of elements), enzymes are used to arrange the correct structure.

dna is found in the nucleus of every cell in the body except red blood cells. germ cells eg eggs only contain half the amount as somatic(body cells)

the genes that are present in a chromosome codes for a protein which  are usually known as enzymes.these enzymes r produced from gene by transcription and translation .transcription is the process in which the dna is transcribed into rna by rna polymerase enzyme .this rna then undergoes translation in the cytoplasm of the cell and produces the enzymes .these enzyme acts in a sequence on the substrate and produces the final product\neg: catabolism of glucose(glycolysis)-glucose breakdown occurs by nearly ten steps involes the participation of nearly 10 enzymes to produce the   final product pyruvic acid

> *How are the codes for proteins carried from the nucleus to the ribosomes?\nmRNA, messenger RNA, is transcribed from the "template" strand of DNA for that particular gene.  The mRNA may leave the nucleus and enter the cytoplasm, where it will encounter a ribosome.\n\n> A single strand of DNA has the bases AGTAAC. Using letters, show a matching DNA strand from this pattern.\nTCATTG\n\n> *How is tRNA used when cells build proteins?\ntRNA is a sequence of three nucelotides bound to the corresponding amino acid.  The ribosomes "read" the mRNA, match it, in reading frame, with the corresponding tRNA, and add the amino acid to the growing polypeptide.\n\n> *You begin as one cell. Compare the DNA in one of your brain cells to the DNA in one of your heart cells\nGenerally speaking, the nuclear DNA in your heart cell will be the same as the nuclear DNA in your brain cell.
