What makes one person differ from the other? Is it physical appearance, personality or mentality? These three factors separate each individual from one another and it is what makes them different. Physical appearance, personality and mentality are made up from the same building blocks which are known as DNA sequences. DNA (deoxyribonucleic acid), is a self replicating material that is found throughout every living organism. It’s a large macromolecule that transforms characteristics into life. DNA is made up two strands that run in opposite directions therefore they are known to be antiparallel. The lagging strand runs in the 5 '-3 ' direction while the leading strand run’s in the 3 '-5 ' direction (International Baccalaureate Organization, 2009). There’s a phosphate group attached by a covalent bond to the carbon atom which is covalently attached to a nucleotide base. The two DNA strands are attached to each other by hydrogen bonds. There are two hydrogen bonds found between Thymine and Cytosine and three hydrogen bonds found between Guanine and cytosine (International Baccalaureate Organization, 2009). Many studies have been done in order to gather information about the human DNA. The sequence of base paring in DNA was determined by The Human Genome project (International Baccalaureate Organization, 2009).
