Hi, need to submit a 1750 words paper on the topic DNA: The Secret of Life. However, we realize that, in human beings, DNA consists of more than a billion elements, which are mostly similar in all humans. The order in which these elements appear determines the availability of elements to build and sustain a being. This can be likened to the order of letters that forms different words and sentences. The four DNA elements combine in a predetermined sequence, that is, A binds with T while C binds with G. This results in the arrangement of elements called base pairs. The ratio of adenine to thymine and guanine to cytosine governs the pattern of DNA. Further, each element attaches itself to a sugar molecule and phosphate molecule to form a nucleotide. These nucleotides are then aligned in two strands to form a double helix, which is spiral in shape running in an anti-parallel manner. These arrangements are referred to as chromosomes, which during the process of DNA replication, divide and are copied or replicated to develop more chromosomes. This results in all cells consisting of enough chromosomes to support life fully. The key element of DNA is that it is capable of replicating itself to make millions of copies. A DNA strand in a double helix is the prototype for copying the series of bases. This is of paramount importance in cell division as the newly created cells need to obtain a similar DNA trait as the old cell. DNA together with macromolecules such as proteins, lipids, and carbohydrates is essential in the establishment and maintenance of any life form, RNA viruses being the exception.

The genetic code is the system used in reading the material contained in DNA. The genetic code spells out the plan of amino acids that form proteins in the body and is studied by replicating existing DNA strands to RNA acid. This is done through a process referred to as transcription. Beings such as animals, fungi, and plants, also referred to as eukaryotic organisms gather their DNA in the nucleus, mitochondria, or chloroplast of their cells. On the other hand, beings such as bacteria and other single-celled organisms commonly referred to as prokaryotes collect their DNA in the cytoplasm. The organization and packing of DNA in cells are tasked with alkaline-based proteins referred to as chromatin. These proteins include histones.
