DNA Liability In Court Cases

these ways work, they aren’t nearly as effective as DNA. With an accuracy of over 99% DNA profiling has become one of the most important, and reliable tools law enforcement has at its disposal. DNA, also known as the blueprint of life, wasn’t described until 1953, when scientists Francis H. C. Crick and James D. Watson identified, and described the structure of DNA, which resembles a twisted ladder or double helix. They also established the role of DNA as the material that makes up the genetic code of…

DNA PROJECT Essay

DNA PROJECT By Julia BRown DNA STRUCTURE The DNA molecule is a long polymer / chain of repeating units. The units are called monomers nucleotides that make up DNA. In the nucleotides there’s phosphate, sugar and a base. There are 4 types of bases in DNA which are the thymine, adenine, cytosine, and guanine. DNA is genetic material that identical molecules could not carry different instructions across all organisms. The same 4 bases are found in the DNA of all organisms but the proportion differs from organism to organism…

DNA’s model structure of Waston-Crick show that a DNA molecule exists in the form of a three-dimensional double helix which consists of two chains are antiparallel with four different types of nitrogen bases. Their observation that two complementary strands linked in a directional chain: beta N-glycosidic bond connects the deoxyribonucleic acid to the nitrogen base, a phosphodiester bond connects one nucleotide to the next and the sugar phosphate backbone is identical in every DNA molecule. The DNA…

Rosalind Franklin: An Uncredited Breakthrough Discovery

Rosalind Franklin: An Uncredited Breakthrough Discovery DNA, or deoxyribonucleic acid, is a component of living beings that is the basis upon which all life revolves around. Therefore, for something as crucial as DNA, to make a discovery that was unprecedented would be a major breakthrough. However, the one who made such a discovery could easily be left behind with little credit for doing so. For Rosalind Franklin, this tragedy was all too common. At a young age, Franklin understood her love…

Biology: Chromosomes the Dna Essay

Eukaryotic Chromosomes The DNA in a eukaryotic cell nucleus is organized as one or more chromosomes that differ in length and shape • During most of the cell’s life, each chromosome consists of one DNA strand (and associated proteins). • When the cell prepares to divide, it duplicates all of its chromosomes, so that both offspring get a full set • Each duplicated chromosome has two DNA strands (sister chromatids) attached to one another at the centromere centromere one chromatid its sister…

Rosalind Else Franklin Research Paper

Born on July 25, 1920 in London, England, Rosalind Else Franklin was a very bright woman and well known for her discovery work in DNA, as well as, being an X-Ray crystallographer. She grew up in a typical Jewish family who was serious when it came to education. Her father was a physics teacher at an education institute for adults, so she grew up being involved in science even at young age. During her childhood years, Franklin was a very smart child and she “earned distinctions in six subjects in…

DNA Profiling

Since the first use of DNA profiling in 1985, the process has seen extensive use in the fields of forensic science and genomics. DNA profiling is a technique predominantly used in forensic science, to identify individuals based on the unique characteristics of their DNA. DNA profiling was developed in 1984 by Sir Alec Jeffreys (see Fig. 1), when he noticed that certain sequences of highly variable DNA which were non-coding, were repeated within human genes (McKie, 2009). With this discovery, he recognised…

Where Do Free Radicals Come From?

unstable and highly reactive. In a process called oxidation, free radicals steal electrons from other molecules—fats, proteins, cell membranes, and even DNA—altering the fundamental structure of the affected molecule. One unbalanced molecule may not sound like a major concern, but oxidation sets off a chain reaction by damaging a cell’s DNA, structure, and ability to function. Over time, oxidative damage accumulates and contributes to aging and a variety of degenerative diseases. [1] WHERE DO FREE…
