1. Discuss how the measurements in Part I (Small Things) relate to the terms accuracy and precision. 2. What is the width of a single DNA molecule in units of centimeters? [The width of the DNA molecule is given by the distance between any two phosphorus atoms recorded in Part II.] 3. Based on your answer to (2), how many DNA molecules would fit across the smallest dimension of the smallest item (from Part I) measured in lab? Write the number in scientific notation. 4. Using the…

This analysis focuses on assessment information provided by an elementary class comprised of 20 students. The results for one particular student named Bobby will also be highlighted in order to analyze and discuss his present developmental word study stage and procedures to support his and his peers spelling acquisition. The words spelled correctly, feature points, and the total feature score will be explained along with the rationalization for grouping the students recorded in this classroom…

Introduction Children begin to learn language as soon as they are born, while they grow their language of speech and skills begin to evolve. Children learn how to communicate their feelings towards others based off of what they have learned from their environment at home. Based on what they learned before school, it affects their development of literacy. Children in the U.S. today, about one-third, lack the ability to learn. This is why language development is very important. Often teachers in…

together to make a sturdy helmet to keep a person's head (two water balloons in a bag with jello) free from a concussion. Our helmets we made were put through a series of tests each time the helmet was dropped from a new height or thrown from a new length. when it came time to actually execute the helmets we learned how important a helmet can be in the process of keeping your head safe, and how getting a helmet in the wrong size or for a different sport could possibly lead to a fatal moment.…

here are classified as VNTR’s (variable number tandem repeats) and RFLP’s (restriction fragment length polymorphism). The first experiment is concerned with DNA polymorphisms that are known as VNTR’s, sections of DNA which have repeated nucleotide base sections in which the repeats vary in number per individual, here the VNTR’s chosen were D1S80 and D3S1358. The second centred on Restriction Fragment Length Polymorphism (RFLP) analysis and how the technique lends itself to the identification of…

The gel electrophoresis apparatus is then turned on and the DNA begins to migrate from the negative side to a positive, which is due to DNA being negatively charged. This process takes Restriction Fragment Length Polymorphisms (RFLPs) and migrates them. The longer the RFLP, the slower it moves and the farther it is up on the gel. The short the RFLP, the faster it travels and the lower it is on the gel. After the gel is ran, it needs to be analyzed to determine…

DNA (deoxyribonucleic acid) is the genetic material that carries the genetic instructions being used in growth, development and reproduction of all living things. DNA has regions called genetic polymorphisms that are used to determine paternity/maternity, kinship, determination of human remains, and inherited diseases. DNA is an example of what forensic use for evidence in a crime. Using regions in the DNA you can determine a “fingerprint” for an individual that can help in a crime, with this…

Discussion When comparing the banding patterns of the crime scene to those of the suspects, the resulting gel indicates that Suspect 2 was at the scene of the crime. Although enzyme 1 produced identical DNA fragments across the gel, enzyme 2 did not. This is evident in lane D and possibly indicates that this enzyme was unable to bind to recognition sites similar to the crime scene DNA in well B. Thus, it produced a DNA fragment smaller in size that travelled further. Since the DNA evidence in…

unrelated entities share the same genetic code. DNA fingerprinting is consists of many common procedures: RFLP (Restriction Fragment Length Polymorphism) utilizes special restriction enzymes to cut portions of the extracted DNA and focuses on repeating sequences of the DNA bases that differs from each individual. Electrophoresis separates the DNA and measures the portions by length. Autoradiography produces an x-ray of the results after the portions are sorted. The scientists then determine the…

other forensic identification processes because it remains the same overtime, unlike fingerprints and has a higher accuracy than biometric iris scanners. The first methods used for DNA profiling for finding out genetics involved restriction fragment length polymorphism (RFLP) analysis. The method involves DNA to be collected from cells and cut into small pieces using a restriction enzyme. This generates thousands of DNA fragments of differing sizes and then separated on the basis of size using…
