    The Human Genome Project was started in the year of 1990 and it was completed in 2003. It was coordinated to by the U.S. Department of Energy and the National Institutes of Health. The goals of this project were to identify all of the genes found on human DNA. To determine the sequences of the 3 billion chemical base pairs that make up the human DNA and to store all the information in databases. Also improve the tools for data analysis.

    This project was initially started by James D. Watson in the year 1990. The root of the project came from the early work on the passing down of traits, such as the ones conducted by Gregor Mendel. Then in 1953, two researchers named Watson and Crick discovered the molecular structure of DNA. But even though the main goal of the Human Genome Project was to understand the genetic makeup of the human genes, it also focused on other organisms such as the fruit fly and laboratory mice.

    Gregor Mendel was the first person to trace characteristics of generations of a living thing. His first experiments were using pea plants and the whole idea was to breed the plants and examine the generations for traits that were being passed down. He chose these plants as his experimental organisms for many reasons. Some of them being that they are capable of self pollination, easy to grow, small in size, and they reproduce quickly with many offspring. They were also capable of cross fertilizing meaning that they could mate with individuals of different kinds, such as other plants.
    Therefore with his results he was able to conclude with certain laws which were named after him. The first law was the law of segregation which is broken into four parts: that alternative versions of the same gene make up for the inherited characteristics, each organism inherits two alleles (one from each parent), dominant traits are the ones expressed in the phenotype, and that each gamete contains only one allele from each parent. The second law was the law of independent assortment in which he states that the inheritance pattern of one trait will not affect the inheritance pattern of another. These were laws have all become the basics of genetics. All science revolves around these laws which make Gregol Mendel the father of genetics.

    Deoxyribonucleic acid, also known as DNA, was discovered in 1953. It is the main carrier of all genetic information. It is made up of nucleotides, which serve as the basic building blocks. Each nucleotide is made up of a five carbon pentose sugar, a phosphate and one of the four existing nitrogenous bases. There are two categories of the nitrogenous bases; purines such as Adenine and Guanine, and pyrimidines, Thymine and Cytosine. The nucleotides pair up in the following manner; adenine with thymine and guanine with cytosine. The nucleotides are held by covalent bonds forming a basis which is referred to as a sugar-phosphate backbone. They are linked in a phosphodiester linkage, which means that 3’ carbon of one sugar is matched with 5’ carbon of another sugar.

    DNA has two strands made up of the sugar-phosphate backbone. The two strands run antiparallel to each other meaning they run in opposite directions. They are also complementary to each other, which means sequence of nucleotides of one stand is matched up perfectly with the sequence of another. The two stands tie together into a double helix structure. There is hydrogen bonding between each nucleotide.
