Conclusions of DH5α DNA transformation with red colonies resistance to ampicillin and the lacZ gene Introduction: In this experiment‚ a plasmid with a gene that has resistance to the antibiotic ampicillin and has lacZ is used to transfer the resistance into E. coli bacteria in red colonies. This same technique is used to give diabetics their insulin‚ and to give dwarfs growth hormones. The point of this lab is to give the groups an idea how DNA can be transformed

The Discovery of the Structure of DNA Determining the structure for DNA was one of the outstanding science achievements of the 20th century. It started in the late 1940’s‚ when scientists were aware that DNA was most likely the molecule of life‚ even though many were sceptical since it was so "simple." They also knew that DNA included different amounts of the four bases: adenine‚ thymine‚ guanine and cytosine (usually abbreviated A‚ T‚ G and C)‚ but nobody knew what the molecule might look like

Comparison chart DNA RNA Stands for: DeoxyriboNucleicAcid RiboNucleicAcid Definition: A nucleic acid that contains the genetic instructions used in the development and functioning of all modern living organisms (scientists believe that RNA may have been the main genetic material in primitive life forms). A single-stranded chain of alternating phosphate and ribose units with the bases Adenine‚ Guanine‚ Cytosine‚ and Uracil bonded to the ribose. RNA molecules are involved in protein synthesis

Ka Zhu The Importance of the Structure of DNA Understanding ideas at a macroscopic scale is simple. Looking at a clock‚ observing and understanding the movements of the hands over the numbered surface are‚ in essence‚ all one requires to use the device. In order for innovation to occur‚ it is imperative to understand the inner workings of the device on a microscopic scale to modulate its properties. Such is the case for many innovations in science‚ from the heat engine to penicillin‚ and is no

Who Discovered DNA? Heather Kane The discovery of deoxyribonucleic acid‚ more commonly known as DNA‚ has been the foundation for much scientific work. This fundamental discovery was credited to James Watson and Francis Crick. Many people believe that another person‚ Rosalind Franklin‚ also played a large role in the research. How much did she contribute to the discovery? Why is her name left unrecognized? This paper will discuss her part in the search and whether her name should appear next to

Scientist extracts DNA to show how it’s useful to solve a crime scene. DNA is the most things to use for solving any crime. Finding DNA is pretty easy to find it can be you’re hair‚ blood‚ or even saliva. Using all that can help investigators to find who the criminal is. Scientist compares the DNA to make sure that their looking for the right person and not to make any mistakes. Scientists extract the DNA when they use blood‚ saliva‚ and other body fluids and tissues. For example the crime investigators

DNA DIGESTION AND ELECTROPHORESIS In this experiment we will be doing a process called as DNA digestion or also known as restriction digest. A restriction digest is a procedure used in molecular biology to prepare DNA for analysis or other processing. It is sometimes termed DNA fragmentation‚ scientists Hartl and Jones describe it this way: This enzymatic technique can be used for cleaving DNA molecules at specific sites‚ ensuring that all DNA fragments that contain a particular sequence have the

DNA Aim This practical procedure allows you to amplify a 460 basepair fragment of DNA from within the control region of the mitochondrial genome. This can be done using three water baths or‚ if one is available‚ a thermal cycler (PCR machine). After it has been amplified‚ the DNA is run on an electrophoresis gel. Note: This method has been adapted from one developed by the Dolan DNA Learning Center at Cold Spring Harbor Laboratory. More details are available from the DNA Learning Center’s

Power of DNA Analysis In the world of medicine and disease there is one disease that is as well known as it is deadly: Cancer. Many people understand the severity of cancer and how it attacks the immune system and ultimately can kill a person. The war on cancer was started in 1971 by President Nixon and this set of four decades worth of study and has lead to a large amount of information being learned about the cancer genome. A new strategy has recently surfaced and is gaining ground‚ DNA analysis
