Christian Chou Mrs. McCarron 12/10/14 A.P Biology Drosophila melanogaster Genetics Introduction: The common fruit fly‚ scientifically named Drosophila melanogaster‚ is used by many in genetic studies. Because they can be easily cultured‚ have a relatively short generation time‚ and are prolific breeders‚ fruit flies are often very popular in genetic investigations. Furthermore‚ mutations and sex are easy to visualize among the fruit flies. Male fruit flies have a smaller abdomen than their female counterparts

In Lab 8‚ we had analyzed remains found at a wooded area near Jonesburg and tried to determine if the bones belonged to a 28-year-old woman who had been reported missing from a city within the vicinity. Upon analysis‚ it was determined that they did belong to a female. However‚ it was not possible to determine if the bones did belong to the missing women. Lab 12 presented the opportunity to genetically analyze the remains found. DNA profiling‚ also referred to as typing and fingerprinting‚ uses genetic

Fruit Fly Genetics Lab Kelly Hernandez 5/31/14 Drosophila melanogaster is a small‚ common fly found near unripe and rotted fruit. It has been in use for over a century to study genetics. Thomas Hunt Morgan was the best biologist studying Drosophila early in the 1900’s. Morgan was the first to discover sex-linkage and genetic recombination‚ which placed the small fly in the forefront of genetic research. Scientists have used Drosophila for many reasons. For one they are very easy to maintain‚

Bio 205 Lab W/8:00 Enzyme II Write-Up Methods: My partner and I ran two experiments to measure the activity of the enzyme horseradish peroxidase under varied conditions. The first of which measured the effects of altered pH levels‚ while the goal of the second was to examine the effects of varied temperatures. To test the effects of pH on horseradish peroxidase‚ we began by zeroing a Spec 20 with 5.0mL of substrate (25mM guiacol) at pH 6.5. Once the Spec 20 was accurately zeroed‚ we added 100μL

Littlefield Simulation Write-up December 7‚ 2011 Operations Management 502 Team 9 Littlefield Lab We began our analysis by searching for bottlenecks that existed in the current system. It was easily identified that major issues existed in the ordering process. Without calculations‚ you could tell the reorder point was too low since the historical plots showed inventory levels at zero for two or more days at a time. The number of jobs in customer orders showed correlating spikes at the same

Keep this growing tip and discard the rest. 6. Break up the root tip with the mounted needle (this is called maceration). Add one small drop of toluidine blue and leave to stain for 2 minutes 7. Cover with the cover slip and blot firmly with several layers of filter/ tissue paper and press gently to spread

Photography Write-Up: Separation The camera I use has been rented from the ERC on a regular basis‚ and is a Canon 600D or 700D. The photo’s i’ve captured for this project were shot on the standard lens‚ with a variety of settings. I also often use a mini LED light with a daylight filter in order to create more depth in the shadows in my images‚ I usually place this somewhere away from the camera in order to create angled shadows instead of images being frontlit. To start this project‚ I experimented
