DNA replication is the process of producing two identical replicas from one original DNA molecule. This biological process occurs in all living organisms and is the basis for biological inheritance. DNA is made up of two strands and each strand of the original DNA molecule serves as a template for the production of the complementary strand, a process referred to as semiconservative replication. Cellular proofreading and error-checking mechanisms ensure near perfect fidelity for DNA replication.
In a cell, DNA replication begins at specific locations, or origins of replication, in the genome. Unwinding of DNA at the origin and synthesis of new strands results in replication forks growing bidirectional from the origin. A number of proteins are associated with the replication fork which helps in terms of the initiation and continuation of DNA synthesis. Most prominently, DNA polymerase synthesizes the new DNA by adding complementary nucleotides to the template strand.
DNA replication can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to initiate DNA synthesis at known sequences in a template DNA molecule. The polymerase chain reaction (PCR), a common laboratory technique, cyclically applies such artificial synthesis to amplify a specific target DNA fragment from a pool of DNA.
Deoxyribonucleic acid (i/diˈɒksiˌraɪboʊnjʊˌkliːɪk, -ˌkleɪɪk/;DNA) is a molecule that carries most of the genetic instructions used in the development, functioning and reproduction of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase—either cytosine (C), guanine (G), adenine (A), or thymine (T)—as well as a monosaccharide sugar called deoxyribose and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. According to base pairing rules (A with T, and C with G), hydrogen bonds bind the nitrogenous bases of the two separate polynucleotide strands to make double-stranded DNA. The total amount of related DNA base pairs on Earth is estimated at 5.0 x 1037, and weighs 50 billion tonnes. In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).
Daily News and Analysis (DNA) is an Indian broadsheet launched in 2005 and published in English from Mumbai, Ahmedabad, Pune, Jaipur, Bengaluru and Indore in India. It is the first English broadsheet daily in India to introduce an all-colour page format. It targets a young readership and is owned and managed by Diligent Media Corporation.
A high-profile advertising campaign with the tagline, "Speak up, it's in your DNA", preceded the birth of Daily News and Analysis in 2005. The context into which the publication was introduced was described by the Indian media as tumultuous, with price cuts and competitive activity occurring.
In an announcement on its front page on 1 February 2010, former editor-in-chief Aditya Sinha announced that DNA would drop its "edit page," the section containing editorials, analysis and opinion.DNA's decision was considered bold and attracted much criticism in the field. DNA subsequently began providing, where appropriate, expert opinion and comments in different pages of the newspaper.
Drew Berry (born 1970 in the United States) is a biomedical animator at the Walter and Eliza Hall Institute of Medical Research in Melbourne, Australia. His scientifically accurate and aesthetically rich visualizations are elucidating cellular and molecular processes for a wide range of audiences. His animations have been shown in exhibitions, multimedia programs and television shows, and have received international recognition including an Emmy (2005) and a BAFTA Award (2004).
Berry received a Bachelor of Science (1993) and Master of Science (1995) degrees from the University of Melbourne, and received training in cell biology as well as in light microscopy and electron microscopy.
Since 1995, Berry has been a biomedical animator at the Walter and Eliza Hall Institute of Medical Research. His 3D and 4D animations have focussed on explaining cellular and molecular processes relevant to research conducted at the institute, in fields including molecular biology, malaria, cell death, cancer biology, hematology and immunology.

Paul Andersen explains how DNA replication ensures that each cell formed during the cell cycle has an exact copy of the DNA. He describes the Meselson-Stahl experiment and how it showed that DNA copies itself through a semi-conservative process. He then explains how multiple enzymes, like DNA polymerase, helicase, primase, ligase, and single strand binding proteins copy DNA. He also differentiates between the leading and the lagging strand. He explains how DNA is anti-parallel in nature and how eukaryotic cells have multiple origins of replication.

This is a form of artificial DNA that self-replicates and evolves thus it can be thought of as alive. They quickly began creating fully artificial humans that were indistinguishable from real ones. This came, however, not without a consequence. They were built with a fail-safe.
