Bahawalpur, Pakistan gnetle_kashif@yahoo.com Abstract. DNA computing is a discipline that aims at harnessing individual molecules at the nano-scopic level for computational purposes. Computation with DNA molecules possesses an inherent interest for researchers in computers and biology. Given its vast parallelism and high-density storage,
DNA computing approaches are employed to solve many problems. DNA has also been explored as an excellent material and a fundamental building block for building large-scale nanostructures, constructing individual nanomechanical devices, and performing computations. Molecular-scale autonomous programmable computers are demonstrated allowing both input and output information to be in molecular form. This paper presents a review of recent advancements in DNA computing and presents major achievements and challenges for researchers in the coming future.
Keywords: DNA Computation, Computing Power, Evolutionary Computing

1. INTRODUCTION
Ever since scientists discovered that conventional silicon based computers have an upper limit in terms of speed, they have been searching for an alternative media with which to solve computational problems. The search led to DNA.
DNA computing is a method of solving computational problems with the help of biological and chemical operations on DNA strand. It was introduced by
Adleman [1]. Since then more and more researchers are motivated by the promising future of this area and start working on it.
DNA is a basic storage medium for all living cells. The main function of DNA is to transmit or absorb the data of life for billion years. Roughly 10 trillion DNA molecules could fit into a space the size of a marble. Since all these molecules can process data

    DNA is the blueprint for life, it is found in the nucleus of cells on the chromosomes. It is found in many cell organelles, such as plasmids in bacteria, chloroplasts in plants, and mitochondria in both plants and animals. DNA helps us to perform many actions in solving crimes, and also helps us to do scientific studies that were not possible until recently. DNA has a double helix structure, its sugar phosphate backbone, made up of deoxyribose and a phosphate group are held together by hydrogen bonds and base pairs. These bases are adenine and guanine, thymine and cytosine. There are coding and non coding parts of DNA, the non coding part is called an intron, this may not seem to have a function but it helps to keep the structure of the helix by coiling, regulates when genes are expressed and is also used in DNA replication. Non-coding regions of DNA between genes are the satellite DNA, this is a simple base sequence repeated many times. It’s not all non-coding DNA though, the coding parts of the DNA are known as exons.…

    DNA is one of the nucleic acids information-containing molecules in the cell (ribonucleic acid, or RNA, is the other nuclei c acid). DNA if found in the nucleus of every human cell. The information is DNA: guides the cells (along with RNA) in making new proteins that determine all of our biological traits. DNA gets passed (copies) from one generation to the next. DNA in a cell is really just a pattern made up of four different parts called nucleotides. Image a set of blocks that has only four shapes, or an alphabet that has only four letters. DNA is a long string of these blocks or letters.…

    Deoxyribonucleic acid (DNA) is a complex biochemical macromolecule that carries genetic information for cellular life forms and some viruses. DNA is also the mechanism through which genetic information from parents is passed on during reproduction. DNA consists of long chains of chemical compounds called nucleotides. Four nucleotides are present in DNA: Adenine (A), Cytosine (C), Guanine (G), and Thymine (T). Certain regions of the DNA are called genes. Most genes encode instructions for building proteins (they're called "protein-coding" genes). These proteins are responsible for carrying out most of the life processes of the organism. Nucleotides in a gene are organized into codons. Codons are groups of three nucleotides and are written as the first letters of their nucleotides (e.g., TAC or GGA). Each codon uniquely encodes a single amino acid, a building block of proteins.…

    Have you ever asked yourself, exactly what is DNA and why is it so important? DNA stands for Deoxyribonucleic Acid and is found in every living thing. We inherit DNA from our parents, half from our mothers and half from our fathers. DNA is made up of sugars, bases, and phosphates and comes in the structure of a double helix which looks like a spiral staircase (Craig Freudenrich, 2007). DNA is found in the genes which are housed in chromosomes. Humans have 46 chromosomes; however, the amount of chromosomes varies from specie to specie. Except in the case of identical twins, DNA is unique…

    DNA is a nucleic acid, which consist of long chains (polymers) of chemical units (monomers) called nucleotide. A molecule of DNA contains two polynucleotides, each a chain of nucleotides. Each nucleotide consists of a nitrogenous base, a sugar, and a phosphate group. Each DNA strand serves as a mold, or template, to guide reproduction of the other strand. There are four different types of nucleotides found in DNA, differing only in the nitrogenous base. DNA is contained in blood, semen, skin cells, tissue, organs, muscle, brain cells, bone, teeth, hair, saliva, mucus, perspiration, fingernails, urine, feces, etc. The four nucleotides are given one letter abbreviations as shorthand for the four bases: A is for adenine, G is for guanine, C is for cytosine, and T is for thymine.…

    DNA is described as “a nucleic acid that carries the genetic information in the cell and is capable of self-reproduction and synthesis of RNA” at “The Free Dictionary”. According to nature.com, DNA is “a double-stranded helix, with the two [long chains of nucleotides] connected by hydrogen bonds.” It is the “molecule of life” and includes different amounts of the four bases (adenine, thymine, guanine, and cytosine). Throughout the years, many other scientists have added to the study, but despite all the newfound knowledge,…

    In recent decades the advancements achieved in bioengineering have helped us develop a better understanding of the origins from which humans and other living creatures spur. The discovery of the Deoxyribonucleic acid (DNA) is the key to all bioengineering. The DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. The main role of DNA molecules is the long-term storage of information. An allele is one of two or more forms of the DNA sequence of a particular gene. Each gene can have different alleles. Sometimes different alleles can result in different traits. Occasionally different DNA sequences of alleles will have the same result in the expression of a gene.…

    Deoxyribonucleic acid (DNA) is the fundamental molecule of life encoding the genetic code for the development and functioning of every living organism and a large variety of viruses. RNA, proteins, and DNA are the main macromolecules, which are necessary for every form of life. The genetic system is encoded in the form of a sequence of nucleotides (guanine, adenine, thymine, and cytosine), which are denoted by the letters G, A, T, and C. Most DNA molecules consist of double-stranded helices, composed of two long polymers made of simple units named nucleotides, molecules with backbones constructed of alternating sugars (deoxyribose) and phosphate groups (relative of phosphoric acid), with the nucleobases (G, A, T, C) joined to the sugars. DNA is a suitable store for biological information, because the DNA backbone resists cleavage and the double-stranded structure allows the molecule to have a built-in duplicate of the encoded data.…
