What Does It Stand For Dna Research Paper

Understanding DNA can take a lot of studying and confusion to even get the general idea of the concept. The structure of DNA is very complicated and complex to understand, but researchers James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin all developed the idea of the DNA structure in 1953. Deoxyribonucleic Acid is found in the nucleus of the cell. It is a double stranded molecule that contains the genetic code and is the main component of chromosomes. DNA is the blueprint of organisms. Nucleotides are the basic unit of DNA and they are made up of sugar, phosphate, and one of the four basis including adenine,

Each human being has something called DNA. DNA is described as genetics and an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms. DNA constructs of two nucleotide strands coiled around each other in a ladder like arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanine, cytosine, and thymine. Each chromosome consist of one continuous thread-like molecule of DNA coiled tightly around proteins and contains a portion of the 6,400,000,000 basepairs that make up your DNA.

Ok let's break DNA down first. DNA stands for Deoxyribonucleic acid. Deoxyribose is referred to the absence of an O in the Carbon 2 of the ribose pentose. DNA is made up of six smaller molecules a five-carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases adenine, thymine, cytosine and guanine. The basic building block of DNA is called a NUCLEOTIDE. A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. In other words, the sugar that makes DNA is ribose a pentose sugar in the case of this molecule DNA its lacking an Oxygen in its carbon 2. Nucleic is referred to its position, our DNA most anyways is located on the nucleus of our cells, the presence of this nucleus is what differs us from Prokaryotes us being Eukaryotes.

DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). It has a double helix shape and contains the sugar component deoxyribose.

A stable DNA structure is formed when the two strands are a constant distance apart. This can only occur when a purine (A or G) on one strand is paired with a pyrimidine (T or C) on the other strand. The purine A can only pair up with the pyrimidine T and the purine G can only pair up with the pyrimidine C. Each letter corresponds to a specific nucleotide base. (Wexler 2) A nucleotide is any part of a group of molecules that, when linked together, form the building blocks of DNA or RNA.

All eukaryotic cells get their genetic information from DNA, which are strands of nucleotides whose order conveys genetic information to the cell. Structurally, DNA looks like a ladder. A DNA strand is made up of a sugar-phosphate backbone (similar to the sides of a ladder, alternating sugar and phosphate) and is connected in the middle with paired purines and pyrimidines (fancy names for four chemicals that make up the steps of the ladder). Scientists refer to the distinctive shape of DNA as "a double helix."

DNA is a series of sugars linked together in a specific order. This specific order of sugars: adenine, thymine, guanine, and cytosine, with its associated base determines the genetic information that a person will have. Each parent supplies the offspring with complementary strands of DNA passed down in tight structures known as chromosomes. The DNA codes for a specific gene and the nucleotides give the exact order of amino acids/proteins. DNA has the shape of a double helix. This shape is like two spirals wrapped around each other. The shape of DNA is essential to the way in which it functions because

DNA, or deoxyribonucleic acid, is found in nearly every single one of the 75 trillion cells that made the human body. Chromosomes are made up of protein and DNA molecules. An in-depth look at these threadlike strands reveals what scientist’s calls the double helix. This large, double-stranded molecule resembles a long, spiraling ladder. The sides of this ladder are made up of four building blocks called nucleotides. Each nucleotide is made of a sugar joined to a phosphate and a base. These bases include Adenine (A), Thymine (T), Guanine (G) and Cytosine (C), “the four letters that make up the DNA alphabet”. Nucleotides pairs up according to strict rules, the A-T and G-C base pairs repeats in various sequences repeatedly, creating the 3 billion

DNA is deoxyribonucleic acid, which is found in almost all living things. DNA serves as a code for the creation and maintenance of new cells within an organism. Within humans, it is found in almost every cell. Although most of our DNA is found within the nucleus of our cells as nuclear DNA, a very small amount of our DNA is also found within the mitochondria as mitochondrial DNA. Because mitochondrial DNA is generally not used for solving crimes, for the purpose of this paper it will be disregarded.

DNA is made up of molecules called nucleotides. Each nucleotide contains: Nitrogen bases Adenine (A), Guanine (G), Cytosine (C), and Thymine (T), Deoxyribose sugar, and one or more phosphate groups. The order of the nitrogen bases determines the genetic code. The information in DNA is stored as a code. DNA is composed of four different types of nucleotides (A,G,C,T) connected by hydrogen bonds, Deoxyribose sugar, and one or more phosphate groups. Nucleotide A with T and C with G pair up to form units called base pairs. The sequence of the nitrogen bases determines the information; similar to the way alphabet letters only appear as words when formed together correctly. It is crucial that each strand of DNA complements each other; this is how DNA replicates. When the DNA molecule is packaged into thread-like structures, they are called chromosomes. (U.S National Library,

DNA stands for deoxy-ribo-nucleic acid or sometimes called a double helix (Stoyles 8). DNA is structured and shaped by the parent’s chromosomes. The DNA made from the parent's chromosomes make a child’s chromosomes. DNA has four bases they are; Adenine, Cytosine, Thymine, and Guanine (Stoyles 8). This order of the bases creates the genetic code. The bases order helps the body know what proteins it needs to make special characteristics for the child. These proteins control and make up cells, muscle movement, and thinking. When a new cell is made a new copy of DNA is formed and this process continues over and over again.

The genetic material is carried by the DNA and is present in the nucleus of every eukaryotic cell and in the mitochondria and chloroplasts. Deoxyribonucleic acid (DNA) is a large macromolecule composed of nucleotides as monomers. Each nucleotide consists of a ribose sugar (pentose 5-carbon sugar), a negatively charged phosphate group that gives the DNA its polarity and acidity, and one of four nitrogenous bases (Adenine, Thymine, Guanine, and Cytosine). Every two nucleotides are linked together by a 3’-5’ phosphodiester bond, and thereby a series of these bonds forms one of the two strands of the double helix. Moreover, the two strands are connected together in an anti-parallel manner by hydrogen bonds, forming the DNA double helix. Whereby Adenine and Thymine are complementary and linked together by two hydrogen bonds, while Guanine and Cytosine are linked by three hydrogen bonds. This DNA molecule is then coiled and accompanied with histone protein to form the chromosomes.

DNA is known as deoxyribonucleic acid, which is a hereditary material that all eukaryotic organisms have. DNA is mostly located in the nucleus of cells but can also be found in mitochondria. The information of DNA is stored as a code made up of four chemicals. Two of these chemicals are purines, the other two pyrimidines. The purines are Adenine and Guanine. The pyrimidines are Thymine and Cytosine and the purines pair with the pyrimidines. Specifically Adenine with Thymine, and Guanine with Cytosine. Every strand of deoxyribonucleic acid uses the same bases, just arranged in different orders. DNA strands are in a shape of a double helix, if you were to get a closer look, you would see nucleotides. A nucleotide are the basic unit of structure for DNA. They consist of a sugar, the base, and phosphate. The phosphate group on the outside,

Essentially, adenine may only bind with thymine with two hydrogen bonds, and guanine may only bind with cytosine with three hydrogen bonds. In broader perspective, purines may only bond with pyrimidines. Adenine and guanines are the purines, due to their double ring molecular structure, while thymine and cytosine are the pyrimidines due to there single ring structure. In addition the strands of DNA are connected together between base pairs, through Hydrogen bonding. While each base pair may only bind with its complimentary base pair, it is the sequence of the base pairs that creates such genetic diversity amongst living organisms around the world. As scientists further investigate the atomic structure and function of DNA, DNA replication is also being further examined. During DNA replication, multiple enzymes, such as DNA Ligase, DNA Helicase, and DNA polymerase assist in unwinding the DNA double strand into single stranded DNA (essentially an unwinding of the DNA in which the hydrogen bonds are broken separating the two strands) which would latter be used as a template for the creation of a new single DNA strand. DNA is thus widely known as the genetic material for almost all living organisms.

Deoxyribonucleic (DNA) is the molecule that hold the genetic information of living things. In our body every cell contains about 2 meters of DNA. DNA is copied every time a cell divides. Deoxyribonucleic (DNA) is made up of two polynucleotide strands. Polynucleotide strands twist around each other, forming a shape that looks like a ladder called a double helix. The two polynucleotide strands run antiaparallel to each other with nitrogenous bases this means that the stands run in opposite directions, parallel to one another. The DNA molecule consists of two backbones chains of sugars and phosphate groups. The organic bases held together by hydrogen bonds. Although bases bonded together are termed paired
