DNA: Interactions between Proteins

Deoxyribonucleic Acid is a molecule that contains the genetic makeup of almost all living organisms. While Deoxyribonucleic Acid, or DNA, has been successfully mapped out, many of its interactions with certain proteins and enzymes have not been fully revealed within the atomic level.
The history and mysteries of DNA continue to fascinate biologists and chemists alike. However, we must question, who was the first to discover DNA, and what scientists have done to further enhance our understanding of it? In short, DNA was first isolated by physician Friedrich Miescher in 1869; in 1937, William Astbury became the first person to produce an x-ray diffraction pattern of the DNA molecule. Sixteen years

Essentially, adenine may only bind with thymine with two hydrogen bonds, and guanine may only bind with cytosine with three hydrogen bonds. In broader perspective, purines may only bond with pyrimidines. Adenine and guanines are the purines, due to their double ring molecular structure, while thymine and cytosine are the pyrimidines due to there single ring structure. In addition the strands of DNA are connected together between base pairs, through Hydrogen bonding. While each base pair may only bind with its complimentary base pair, it is the sequence of the base pairs that creates such genetic diversity amongst living organisms around the world. As scientists further investigate the atomic structure and function of DNA, DNA replication is also being further examined. During DNA replication, multiple enzymes, such as DNA Ligase, DNA Helicase, and DNA polymerase assist in unwinding the DNA double strand into single stranded DNA (essentially an unwinding of the DNA in which the hydrogen bonds are broken separating the two strands) which would latter be used as a template for the creation of a new single DNA strand. DNA is thus widely known as the genetic material for almost all living organisms. Although DNA replication is in general understood, its atomic structure and interactions (between DNA and its proteins and enzymes) are not. Hence, we must begin to
