...DNA DNA represents the genetic material within a cell that provides the basic blueprint for living cells, somewhat like a program for creating biological structures. Though DNA has received much attention in the media in recent years, it is important to note that the discovery and implementation of most DNA techniques only occurred as recently as the middle of the twentieth century. Understanding of the history, structure, and function of DNA is critical to modern science. Though DNA had long been known to exist is the cell, the structure and importance of the compound was not fully...

...DNA: The Basis of Life The question of “What is life, and what is it made of” has been asked to the point of making it cliche,if not ubiquitous, yet a multitude of answers persist. Life could be defined as a potential, as a response to external stimuli, or even as an indefinable feeling, yet none of these answers attempts to solve the question of what actually drives the biological engine of our bodies that keeps us breathing, pumping blood, and absorbing food. On April 25th, 1953, the now famous scientific pair of Watson and Crick attempted to finally answer this question (Fredholm). They claimed that an elegant molecule called deoxyribonucleic acid, or...

...DNA Fingerprinting Introduction DNA as we all know is the basic building structure of every living thing present on earth. It has been scientifically proved that it is the DNA that gives us our characters, both phenotypic and genotypic. If the there is some sort of problem i.e. mutation in the DNA, it would lead to altered characters or even lead to abnormalities (Burke 1991). The DNA sequence of every individual is specific and is generally passed on from parents to their offspring. The basic structure of a DNA consists of four Nucleotide bases i.e. Adenine, Thymine, Guanine and Cytosine. These four bases pair with each other in a unique manner i.e. Adenine-Thymine and Guanine-Cytosine... ?Submitted DNA ...

...DNA Fingerprinting DNA (Deoxyribonucleic acid) is a chemical structure which forms chromosomes. A set of chromosomes that determines a specific trait, character or quality is referred to as genes. In a structure form, DAN is a double helix: genetic materials of two strands that are spiraled around one another. Every strand is composed of nucleotides, a sequence of bases. A base can be one of the four chemicals, adenine, thymine, cytosine, or guanine. The two DNA strands are connected to every base. Bases can only bond with each other as follows: Guanine (G) can only bond with cytosine (C), and adenine (A) can only bond with thymine (T) (Tabet 83). For example, if a single DNA strand...
