“Finding Your Roots”
We, people are related species that have lot of things in common. We all originated from a same ancestor Homo sapiens who were mutual parents in the past. When we compare one another genetically, we both possess 99.9% of genome sequence identical. It depicts that we all originated from a same blood and entirely related to one another. If we track our ancestors, long way behind we will find the same parents in our genome identity. Miraculously, the remaining one tenth of the DNA sequence is the genome that makes us what we are and an identical around the globe. That one tenth percent changes our appearance between one another, behavior and understanding and makes us powerful or incompetent. Due to this, study of DNA and its applications has become more and more important hovering lot of attention to carry out DNA usages for identification of inheritance, legal issues, study of human behavior and many other medical applications. DNA commonly known as Deoxyribonucleic Acid is a heredity materials in a human and almost all living organisms found in the earth. DNA is a double helix structure consisting of nucleotides and nucleosides with sugar and phosphate base that carries genetic materials from parents to its offspring creating completely a unique human body. DNA comprises of a long molecules corresponding four different nucleotides i.e. adenine, guanine, cytosine and thymine also commonly called as “A”, “G”, “C” and “T” which plays an important role for an identification of who they are and where they come from. DNA importance and its usages were unknown until James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin came up with an explanation of DNA in 1953. After its discovery, DNA has significantly become a great achievement for all mankind as it provides more understandings of human origin, evolution and its behavior in the past, present and in the future. DNA profiling is a technique that is used by forensic scientists to...
