Materials and methods 1. Raw materials Full ripe cactus Opuntia dillenii fruits were harvested from the orchard of Faculty of Agriculture‚ Suez Canal University‚ Ismailia Governorate‚ Egypt during December 2014. Fruits were washed and glochides and the two distal parts (top and bottom parts) were removed. The fruits were mashed in a mixer by mixing for 15 s. After that‚ the seeds were separated‚ washed and dried by hot air in a convective dryer (WT-binder‚ Type F115‚ Germany) at 50 ºC‚ air velocity

Drosophila melanogaster: Mutant Fruit Flies Jessica E. Phillips Genetics 3301 April 13‚ 2012 Introduction: Drosophila melanogaster better known as the fruit fly can be found near rotting fruits‚ vegetables‚ or anywhere where there is food that has rotted and or fermented. (Potter‚ 2010) D. melanogaster has four different stages in its life cycle. The first stage of D. melanogaster is the egg which can last for about one day; then turns into a larva. The larva stage last for about 7-8 days

A Study Of Inheritable Traits in Fruit Flies INTRODUCTION The Drosophila melanogaster‚ more commonly known as the fruit fly‚ is a popular species used in genetic experiments. In fact‚ Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can

After the chi-squared values were found in each week (table 1)‚ in the third generation where the chi-squared was found to be 0.32 which most likely fall between the two values of 0.148 and 0.455. These two values correspond to a probability values of 0.70 and 0.50‚ and these two values lay to the left of the p- value of 0.05‚ which means the null hypothesis presented

Genetic engineering is a type of engineering where genes are modified to find cures‚ diseases‚ and more. Genetic engineering uses the central dogma‚ which is the idea of taking. DNA transcribing it into RNA translates it into protein and expressing it as a trait. Recombinant plasmids are when DNA fragments are inserted into a plasmid vector. The recognition site is where the plasmid gets cut by the restriction enzyme which is an enzyme that cuts a DNA molecule. Recombinant DNA is the DNA being inserted

research is using this information to reduce the amount of anoxia related stress humans with pulmonary diseases experience. Methods Each condition was tested with a separate single group of D. melanogaster (cold bath - 8 flies and warm bath – 11 flies)‚ and all of the flies used were approximately 1-9 day old males. Each group of D. melanogaster was held in a container that provided adequate nutrients prior to the experiment‚ and then transferred to a drowning container that held no nutrients.

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

Too many house-flies are coming into people’s homes during the summer when they have their doors and windows open. This is a problem for the people living in these homes as house-flies carry diseases that they transmit onto food around the home. We need to come up with a solution that decreases the number of house-flies coming into the home while allowing people to keep their doors open. After considering numerous ideas I concluded that the best way to do this is via a eugenol based fly spray. Due to
