Genetic Testing
Genetic testing is a term used to refer to some type of medical test carried out to identify changes in genes, chromosomes or proteins. It … to refer to some type of medical test carried out to identify changes in genes, chromosomes or proteins. It is also known as dna testing as it helps to detect changes in chromosome structure or dna sequence. Over the past few decades, this biotechnology has become more popular to an extent that various genetic tests have emerged and expanded. … few decades, this biotechnology has become more popular to an extent that various genetic tests have emerged and expanded. Despite its popularity, genetic testing is associated with some risks and limitations including physical risks. Consequently, numerous arguments have been raised to support and disapprove the use of … of this biotechnology. This paper examines reasons for and against the use of this technology and……

Cystic Fibrosis
… immunoreactive trypsinogen (IRT) in blood. This test is relevant because persons with CF has abnormally high levels of IRT in their blood.
ii. dna test – because CF is a genetic disorder, it means there is a gene anomaly, which can be detected through dna testing. A dna test therefore looks for the abnormal gene in the CFTR gene.
iii. Sweat test – this test determines the level of salt(chloride) in … the above three, CF can also be diagnosed in an unborn child through prenatal diagnosis test. This test uses mutated CFTR genes, by testing a sample of amniotic fluid or tissue from the placenta. However, incase these tests indicate a positive test for CF, additional test has … April, 2014.

Conclusion
CF is a genetic disease that affects lungs. Diagnosis can be done through blood test, dna test, sweat test, and through……

Scientific Method Applied To Forensic Science Paper
...Dna testing The Role of Forensic Science in Crime Scene Investigation
The scientific method begins with the identification of a problem. Questions are asked, data is collected, a hypothesis is formed and then tested. The scientific method is essentially no different from the kind of investigative work that investigators of a crime scene do on a daily basis. They a faced with a problem: a crime has occurred. The questions they must ask are: what happened, why, when, who was involved, where did it occur, and how did it happen? They collect data and using forensic science to analyze the data, they come up with a narrative that answers those questions (Shaler, 2011). Lab work helps to verify the story by providing more evidence that can give more details. This paper will show how the scientific method is applied to forensic science.
The forensic scientific method consists of five steps:
1. Acquisition……

Can Aging Be Reversed
… at the most basic level of human cell lines.” Previous scientists had theorized that aging was the result of a mutation in the dna structure. What the researchers in Japan discovered was that there was no mutation to be found: they compared the dna of elderly persons with the dna of 12 year olds and found the sequence structure to be the same. The only difference was reduced cellular respiration, which the researchers … the same. The only difference was reduced cellular respiration, which the researchers linked to epigenetic regulation—basically “changes that alter the physical structure of dna without affecting the dna sequence itself, causing genes to be turned on or off” (Mack, 2015). In essence, all that may be required to reverse the aging ……
