DNA barcoding

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 well D belongs to Suspect 1, it is apparent that they are not related to the crime. However, when the DNA of Suspect 2 was cut with enzyme 2, a DNA match between the suspect DNA…

In a discussion with Luhan Yang (a “young postdoctoral scientist”), Antonio Regalado learns that altering the DNA in the “germ line” (egg and sperm) or in the actual embryo can help to possibly “correct disease genes and pass those genetic fixes on to future generations.” These diseases could include those like cystic fibrosis and Alzheimer’s. “Such history-making…

science to law by analyzing DNA for legal evidence. DNA profiling is the predominant application and forensic science, DNA profiling allows us to take more than one sample of an unknown DNA specimen and determine if it has the same genetic match. Moreover, DNA profiling is to help determine and solve crime scenes such as murders, assaults, and rapes. The technique used for analyzing DNA is restriction fragment length polymorphism testing. It restricts the enzyme, which cuts DNA at specific…

As a DNA day ambassador, visiting high school classrooms and speaking about research opportunities at the University of Kansas including ways to get involved in science programs and activities, I was particularly astounded with how one session related to my own history. Entering the classroom and anticipating 25-30 students, only about eight were present. The teacher expected my confusion as this was not the estimated number. Rather than requiring her whole class to attend the workshop, she made…

Food Biotechnology is a process by which foods are created or modified to enhance crop production, nutritional value, safety, and/or taste. These foods are considered genetically engineered (GE), or genetically modified (GM). Genetic engineering modifies the genetic material of living cells to produce new substances or perform new functions. As with most “new” technological advances, genetic engineering has its advantages and disadvantages and is currently a hot topic of debate with regard to…

and the Macromolecules. I’ll start with the Macromolecules. These molecules are the four molecules all living things need to survive. The four molecules are Proteins, DNA, Carbohydrates, and Lipids. Each of these molecules is made of Carbon, Hydrogen, and Oxygen at the very least. Proteins have Nitrogen as an added element, and DNA has Phosphate and Nitrogen. The base structure of each molecule has a carbon skeleton. This means that structures have Carbon as the base, in diagrams the carbon…

This discussion inside psychology is involved with parts of performances and inventions. Nature is what we reflect on and which is influenced by genetic birth-right and other natural factors. Nurture is mostly taken from the effect of outside factors after opening the product of contact, knowledge and education of an individual. The nature-nurture debate is concerned with the relative contribution that both influences make to human behavior. The certain physical characteristics are biologically…

Year 10 Research Task – Genetics and Evolution Gene Therapy What is Gene Therapy? ‘Therapeutic gene therapy’ is an experimental technique that uses genes to treat or prevent disease. Inheriting faulty genes causes a wide range of conditions, including cystic fibrosis and haemophilia, and may cause susceptibility to some cancers. It is an experimental technique with aims to rid genetic conditions at their source. Several approaches are being tested - - Replacement of a mutated gene with a working…

similarities. Prokaryotic cells, although simpler and smaller, make up most life. A nucleoid region contains a loop of nucleic acids known as a DNA plasmid. Prokaryotic cells contain simplified ribosomes which free float in cytoplasm all bound by a cell membrane and wall. Eukaryotes, on the other hand, contain complex double membraned organelles, complex DNA (arranged on chromosomes), and a nucleus. Due to the efficiency required of the cell, it is significantly larger than prokaryotes,…

The result from the transformation process showed no colony growth on the agar plate, which means no plasmid DNA got inserted into the vector (Table 1). Thus, the transformation was considered unsuccessful. With that being said, the gene was not transferred among the bacterial cells. The reason could have been that the agar plate had a strong concentration of antimicrobial drug, so the bacteria may have been unable to grow under such condition. Another reason could be that the cell did not get…
