Dna Molecule Von Laue
1,115 wordsIn The Double Helix, a reader can find James D. Watson's first hand accounts of the competitive race in science that led to the discovery of the structure of the DNA molecule. The DNA research Watson and his colleagues took part in demanded knowledge in many areas of expertise, but the most important area was that of X-ray analysis. By creating photographic two dimensional pictures of the three dimensional DNA molecule, Watson and his team were able to analyze these pictures and determine that D...

Nitrogenous Bases Amino Acids
999 wordsDeoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cel...

Double Helix X Ray
784 wordsBorn on July 25, 1920 in London, England, Rosalind Elise Franklin was a catalyst to many other scientists in the field of genetics. Using coal and carbon as subjects, Franklin discovered the double helix of DNA, the shape that two linear strands of DNA assume when bonded together. In 1945, Franklin received her Ph. D in physical chemistry from Cambridge University. The next year she went to Paris and worked in the Laboratoire Central des Services Chimiques de Left until 1950 where she concentrat...

Institute Of Technology Hydrogen Bonding
1,257 wordsChemist Linus Pauling; born in Portland, Ore. After taking his Ph. D. at the California Institute of Technology (1925) and then two years of study abroad, he returned to that institution for most of his professional career (1927 -- 63). Details of those years are as follows: At the California Institute of Technology his advisor was Roscoe Dickinson, whose area of expertise was X-ray crystallography. At this time Dickinson was investigating the crystal structure of various minerals. In his work w...

History Of The Human Genome Project
1,354 wordsThe Human Genome Project (HGP) is an international research effort to decipher the entire human genome and understand the unique hereditary instructions that each person possesses. The HGP is a jointly funded project by the U. S. Department of Energy (DOE) and the National Institutes of Health (NIH) with additional research done by the National (NHGRI). The project, launched in 1990, was originally planned to last 15 years, but rapid advances in technology have accelerated the expected completio...

Dna Gel Electrophoresis Research
1,724 wordsThe main objective of this lab was to identify unknown plasmids by observation of their genotype and phenotype. We observed the plasmids phenotype by using it to transform bacteria. When the plasmid is in a bacterial host the antibiotic resistance gene can be expressed and impart resistance to the host. We also analyzed the genotype of the unknown plasmid by performing a variety of molecular genetic techniques such as predigestion, electrophoresis in arose gel, staining with ethidium bromide, an...

Nucleic Acid Base Pairs
536 wordsThe article, "Structure for Deoxyribose Nucleic Acid", written by Watson and Crick, was a stepping stone on the path of discovery for the building blocks of life. In this article, Watson and Crick briefly state previous theories on the structure of DNA were incorrect in certain aspects but correct in others. Watson and Crick later went on to describe their version of a double helical structured DNA. They indirectly state the importance of their discovery which later them to winning the noble pri...

Rosalind Franklin, a woman of great scientific creativity, the so-called Woman Scientist of DNA was born on July 25, 1920. Her parents Muriel Way Franklin and merchant banker Ellis Franklin, belonged to well-respected Jewish families. Her family often conversed about a lot of things and there were family discussions and debates that honed Franklins logical mind such that Rosalind learned to a...

Dna Fingerprinting Nucleic Acids
4,853 wordsBefore the dawn of the 20 th century, the central role played by one complicated molecule in the shape of all living things was one of natures best-kept secrets. (The History 100) DNA (Deoxyribonucleic Acid), is the nucleic acid found in the nuclei of all cells. It is considered as a gene. (Websters Dictionary 257) Before the year of 1953, no one knew that DNA was going to be the great architect of life (The Histroy 100). It was two intelligent men that discovered natures secret, James Watson an...

Base Pairs Double Helix
610 wordsThe molecule responsible for the transformation of characteristics form one generation to the next is called DNA. The genetic material, located in the chromosomes is a combination of acid and histones. DNA is made up of units called nucleotides. Nucleotides are made up of 3 components, a five carbon sugar (deoxyribose), a phosphate group, and a nitrogenous base. This base can be either adenine, guanine, thymine or cytosine. There are 2 strands of nucleotides in a double-helix they are anti-paral...

Double Helix Cell Divides Cells
250 wordsScientists Find New Lease of Life Scientists in the United States say they have been able to make human cells live longer by altering their genetic material. The research may offer renewed hope for age-related illnesses and the fight against cancer. What Happens When chromosomes divide they go through a process called DNA replication. The double helix separates and unwinds. When the double helix has completely separated new nucleotides complete the base pairings. Then the new phosphate backbones...

Deoxyribose Sugar And A Phosphate Sugar And A Phosphate Group Dna
273 wordsDNA Structure DNA is a double stranded molecule twisted into a helix. Each spiraling strand is comprised of a sugar phosphate backbone and attached bases connected to a complimentary strand. The complimentary strand is connected by non-covalent hydrogen bonding between paired bases. The bases are adenine, thymine, cosine, and gaining. The fundamental building block of DNA is the nucleotide. The nucleotide has three parts. A nitrogen-containing pyrimidine or purine base, a deoxyribose sugar, and ...

Nucleic Acids Double Helix
1,905 wordsDouble Helix A review of Watson, James D. The Double Helix. New York: Atheneum, 1968. James Watsons account of the events that led to the discovery of the structure of deoxyribose nucleic acid (DNA) is a very witty narrative, and shines light on the nature of scientists. Watson describes the many key events that led to the eventual discovery of the structure of DNA in a scientific manner, while including many experiences in his life that happened at the same time which really have no great signi...

Gregor Mendel Nitrogenous Bases
2,810 wordsIn the past few years, genetic engineering and cloning has come a long way. In a 1968 World Encyclopedia, genetics is described as the science of in-heritage (World Encyclopedia, pg. 84), and only refers to the original pea work by Gregor Mendel as the most recent experiments and references. The expand-tion of what genetics is does not take the space of half a page. In 1978, another encyclopedia has ten pages on the subject, though it focuses on plant genetic manipulation. As defined in Biology ...

Protein Synthesis Amino Acids
788 wordsProtein synthesis is one of the most fundamental biological processes. To start off, a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described, a person must know what proteins are made out of. There are four basic levels of protein organization. The first is primary structure, followed by secondary structure, then tertiary structure, and the last level is quaternary structure. Once someone unders...
