Introduction A sample of DNA found in a crime scene was provided along with five suspects. Their DNA was then processed using restriction enzymes and Agarose Gel Electrophoresis. The objective of this lab was to match a criminals DNA to a crime scene using restriction enzymes EcoRI and Pstl with Agarose gel electrophoresis. Restriction enzymes cut DNA at a specific base pair site recognized by the enzyme‚ which then turns one single strand of DNA into many fragmented strands of DNA. EcoRI recognizes

Molecular gastronomy is a subdiscipline of food science that seeks to investigate‚ explain and make practical use of the physical and chemical transformations of ingredients that occur while cooking‚ as well as the social‚ artistic and technical components of culinary and gastronomic phenomena in general.[4] Molecular gastronomy is a modern style of cooking‚ which is practiced by both scientists and food professionals in many professional kitchens and labs and takes advantage of many technical innovations

1. Living organisms play an important role in the recycling of many elements within an ecosystem. One such way this idea can be proven is through the study of carbon in an ecosystem. Plants‚ for starters‚ are a major part of this carbon cycle. During photosynthesis‚ plants remove carbon dioxide from the atmosphere and release oxygen as a waste product. Another major contributor to this vital cycle is the human being. The average human being goes through respiration each day to help maintain
