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.

study of the substances found in living organisms, and of the chemical reactions underlying life processes. This science is a branch of both chemistry and biology; the prefix bio- comes from bios, the Greek word for “life.” The chief goal of biochemistry is to understand the structure and behavior of biomolecules. These are the carbon-containing compounds that make up the various parts of the living cell and carry out the chemical reactions that enable it to grow, maintain and reproduce itself, and use and store energy.\n\nA vast array of biomolecules is present in the cell. The structure of each biomolecule determines in what chemical reactions it is able to participate, and hence what role it plays in the cell's life processes. Among the most important classes of biomolecules are nucleic acids, proteins, carbohydrates, and lipids.\n\nNucleic acids are responsible for storing and transferring genetic information. They are enormous molecules made up of long strands of subunits, called bases, that are arranged in a precise sequence. These are “read” by other components of the cell and used as a guide in making proteins.\n\nProteins (see Protein) are large molecules built up of small subunits called amino acids. Using only 20 different amino acids, a cell constructs thousands of different proteins, each of which has a highly specialized role in the cell. The proteins of greatest interest to biochemists are the enzymes (see Enzyme), which are the “worker” molecules of the cell. These enzymes serve as promoters, or catalysts, of chemical reactions.\n\nCarbohydrates (see Carbohydrate) are the basic fuel molecules of the cell. They contain carbon, hydrogen, and oxygen in approximately equal amounts. Green plants and some bacteria use a process known as photosynthesis to make simple carbohydrates (sugars) from carbon dioxide, water, and sunlight. Animals, however, obtain their carbohydrates from foods. Once a cell possesses carbohydrates, it may break them down to yield chemical energy or use them as raw material to produce other biomolecules.\n\nLipids are fatty substances that play a variety of roles in the cell. Some are held in storage for use as high-energy fuel; others serve as essential components of the cell membrane.\n\nBiomolecules of many other types are also found in cells. These compounds perform such diverse duties as transporting energy from one location in the cell to another, harnessing the energy of sunlight to drive chemical reactions, and serving as helper molecules (cofactors) for enzyme action. All these biomolecules, and the cell itself, are in a state of constant change. In fact, a cell cannot maintain its health unless it is continually forming and breaking down proteins, carbohydrates, and lipids; repairing damaged nucleic acids; and using and storing energy. These active, energy-linked processes of change are collectively called metabolism. One major aim of biochemistry is to understand metabolism well enough to predict and control changes that occur in cells. Biochemical studies have yielded such benefits as treatments for many metabolic diseases, antibiotics to combat bacteria, and methods to boost industrial and agricultural productivity. These advances have been augmented in recent years by the use of genetic engineering techniques.

Mitochondrial DNA (mtDNA) is DNA that is located in mitochondria. This is in contrast to most DNA of eukaryotic organisms, which is found in the nucleus. Virtually 100% of the mtDNA contribution to a conceptus is inherited from the mother.\n\nUnlike most of the cell, the function of which is defined by nuclear DNA, mitochondria have their own DNA and are assumed to have evolved separately. Human mitochondrial DNA consists of 5-10 rings of DNA and appears to carry 16,568 base pairs with 37 genes (13 proteins, 22 tRNAs and two rRNAs) which are concerned with the production of proteins involved in cellular respiration. However many proteins found in the mitochondria are encoded by nuclear DNA: some, if not most, are thought to have been originally part of the mitochondrial DNA but have since been transferred to the nucleus during evolution.\n\nThere is little change in the mtDNA from parent to offspring, unlike nuclear DNA which changes by 50% each generation. Since the mutation rate is easily measured, mtDNA is a powerful tool for tracking matrilineage, and has been used in this role for tracking many species back hundreds of generations.\n\n\nBoth chloroplast and mitochondria need variety of enzymes for different metabolic reactions.So during evolution a separate DNA is needed for it.Chloroplast is so called a cell inside a cell.

> *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.

you use a 3d molecular bio particle scanner.  most of your high end medical research facilities will have one. just call and ask for scanning

The lipid parts have a cation binding site to bind with the negative charges of the DNA.  The final complex is called a liposome.  \n\nIt then carries the DNA into cell and into the nucleus.  You still have to use a bunch of reagents in the process.  This is just from my research background.  The specifics are long.  You can email me for them

In cell biology, the nucleus (from Latin nucleus or nuculeus, kernel) is found in all eukaryotic cells and contains the nuclear genes which form most of the cell's genetic material. Nuclei have two primary functions: to control chemical reactions within the cytoplasm and to store information needed for cellular division.

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
