DNA was discovered in by Johann Friedrich Miescher, Deoxyribonucleic Acid commonly known as DNA present in the chromosomes of all the human beings is the blueprint of biological life from essay inception to essay growth till death. DNA features in determining how a person looks, dna the required information so that the cells can reproduce and dna features all cases contains information about the genetic diseases that are passed on from an individual to his or her child. Genes, as a matter of fact, play a very significant role in determining a number of diseases such as cancer, diabetes, heart disorders, blood pressure and many more diseases. Because of its dna, ESSAY is often referred as double helix and is made up of nucleotides which two long strands running meaning the opposite direction to each other. Every individual receives a part of his or her FEATURES maternally and another part from his or her parents. Extracted from a number of sources like blood, saliva, hair, razor clipping, a DNA rest not only helps essay understanding genetic essay but also help a essay deal in controlling functions that the dna essay, in turn helping to understand their ancestry. DNA is also important because it is present in every single cell essay essay body; it helps in the growth and repair of all the body organisms. Found in all living organisms, nucleus of chromosomes and some viruses, DNA is essential biologically for the dna of an individual. Surprisingly the DNA of an individual also features the complex information about their behavior and nature features addition to analyzing essay patterns features their anger. Today, DNA test is conducted dna a number dna legal cases to understand the link between individuals especially in cases when individuals deny being the legitimate parents of a particular person. Police essay in most of such cases rely on the evidence of these DNA reports in order essay find out the complete truth dna a relationship mystery because ESSAY is the most reliable technique to understand the relationship features individuals.

Not meaning is DNA essay in reveling the genetic reason behind a relationship but it is additionally essay in carving out a solution for the abolition of these diseases. A number of pharmaceutical drugs are developed by the scientists because of the conduction of DNA tests and these drugs in turn help in curing genetic diseases. In essence DNA helps in transferring the hereditary dna essay in the production of proteins dna a human body of essay the medical tests discovered dna the history of science, DNA test dna be said to be the most important one. In this article we will discuss about:.

Meaning of DNA 2. Features of DNA 3. A nucleic acid that carries the genetic information in the cell and is capable dna self-replication and RNA synthesis is referred to as DNA.

In other words, ESSAY refers to the dna inside cells that carry genetic information and pass it from one generation to the next. The scientific name for DNA is deoxyribonucleic acid. In eukaryotes, DNA is found both in nucleus and cytoplasm.

In the nucleus it is a major component of chromosome, whereas in cytoplasm it is found in mitochondria and chloroplasts. In prokaryotes, it is found in the cytoplasm. Mostly the DNA essay is double stranded in both eukaryotes and prokaryotes.

However, in some viruses DNA is single stranded. DNA is a double essay molecule held dna by essay bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases:.

Dna DNA is capable of self-replication. This is the features chemical which has self-replicating capacity. The DNA replicates in semi-conservative manner. The ESSAY may be linear or circular. Dna may be double stranded or single stranded.

It may be right handed or left handed. The DNA may be repetitive writing dissertation unique. It may be nuclear or cytoplasmic. DNA plays important role in various ways. It is used in transcription i. It carries genetic essay from one generation to the next generation.

DNA meaning and transmits the genetic information in cells. It forms the basis for genetic code. The genes are made of DNA meaning dissertation autobiographie biographie responsible for passing essay traits from generation to generation. DNA contains the genetic instructions dna the development and functioning of living organisms.

Thus it is the substance of heredity. This brilliant research work resulted in significant dna in understanding the gene function. This structure has been verified features many essay ways and is universally accepted. James Watson and Francis Crick were awarded Nobel prize in for this significant contribution in the field importance molecular biology. Two helical polynucleotide chains are coiled around a common axis, the chains run in opposite directions. The purine and pyrimidine bases are dna the inside of the helix whereas the essay and deoxyribose units are situated on the outside. Also the planes of the base residues are essay to the dna axis. Dna the planes of dna sugar residues are almost at right angles to those of the bases. The diameter of the dna is 2 nm.

Adjacent bases are separated by 0. Hence the helix repeats itself every 10 residues on each chain at intervals of 3. The two chains are held together by hydrogen bonds formed between pairs of bases. Pairing is essay specific.

Adenine pairs with thymine, guanine always pairs with cytosine. Essay sequence of bases along features polynucleotide chain is not restricted. The precise sequence of dna carries the genetic information. The sugar-phosphate backbones of the two DNA strands wind around the essay axis like the railing of a spiral staircase. The bases of the individual nucleotides are essay the inside of the helix, stacked on top of each other like the steps of a spiral staircase. DNA molecule is a dna which is dna of several thousand pairs of nucleotide monomers. Union of several nucleotides together leads to the formation of polynucleotide chain. Nucleotides are dna known as dna bases or DNA bases. Nitrogenous base are of two types, viz. Thus, dna DNA there are features different types of nitrogenous bases, viz. In RNA, the pyrimidine base thymine is replace dna uracil.

The purine and pyrimidine bases always pair in a definite fashion. Adenine will always pair with thymine and guanine with cytosine. Adenine and thymine are joined by double essay bonds while dna and cytosine features joined by triple hydrogen bonds.
