info in my DNA become my traits? This is a question that has been asked by many over the course of history.To answer this question we need to answer three essential questions‚ the first‚ how did we get our DNA‚ how did we go form one cell to trillions‚ and how did DNA become our traits. There is one essential driver to all of this‚ DNA‚ to understand DNA‚ we need to know what DNA is. DNA is two strands that contain genetic information in four bases‚ adenine‚ guanine‚ cytosine and thymine. DNA is located

experiment would be how the Restriction Endonucleases cleave the strands of DNA. For this experiment‚ pBR322 was the specimen to use. Restriction Endonucleases work by cleaving the sugar phosphate backbone of specific DNA sites. Restriction enzymes that have been isolated from bacteria have a defensive role. This idea is illustrated when an attacking foreign cell DNA is trying to alter the bacteria; restriction enzymes cleave the DNA rendering it inert. The second part of the experiment deals with Gel

Electrophoresis and DNA fingerprinting Jani Lynette Hagen October 31‚2014 U74644799 Electrophoresis is a technique which uses an electric field to separate molecules‚ allowing for identification and characterization of the molecules. It is commonly used to separate nucleic acids and protein molecules of various sizes. To prepare the gel for electrophoresis the amount of agrose needed must be calculated. For a 0.8 percent gel 0.8 grams of agrose is necessary per 100 ml of buffer. The DNA fingerprinting

MULTIPLE EXTRACTION OF CAFFEINE FROM DRIED TEA LEAVES USING DICHLOROMETHANE Delos Reyes‚ K.‚ Dizon‚ G.J.‚ Enriquez‚ J.R.‚ Estrada‚ G. and Garcia C. Group 4 2G Med Tech Organic Chemistry Laboratory ABSTRACT Caffeine was extracted from dried tea leaves by multiple extraction technique. 10g of tea leaves was boiled in a solution of 4.4 g anhydrous sodium carbonate and 100ml distilled water and was extracted three times using 20 ml of dichloromethane. Theresidue was collected by decanting

Radioisotopic labels would be used in experiments to identify semi-conservative replication in prokaryotes. Because we anticipated that a labeled DNA would have different density with unlabeled‚ which means‚ by analyzing the different density of DNAs‚ we can determine which of DNA is labeled‚ half-labeled or unlabeled. To this end‚ I will use c13 label the bacteria and abruptly change carbon source with C12. Then I will collect four samples in different time and analyze the results from centrifugal

Can you expect to extract more DNA from a strawberry or kiwi fruit? Introduction: In the experiment we were inspecting the amount of genetic materials in fruits with different numbers of chromosomes. In the experiment‚ we mashed up a strawberry/kiwi fruit (See appendix 1 figure 2) added extraction butter and ethanol to extract the DNA. A chromosome is a long thread-like cluster of genes in the nucleus. DNA (deoxyribonucleic acid)‚ a self-replicating material which is present in nearly all living

Abstract The purpose of this experiment was to perform a liquid-liquid extraction method to extract the caffeine from the tea bags that were provided‚ and then recrystallize the caffeine. The solvents used in the experiment were an aqueous sodium carbonate and dichloromethane (DCM). Anhydrous calcium chloride pellets were used to dry the solution and emulsion layer and the DCM was then decanted. After washing the anhydrous calcium chloride pellets with more DCM‚ the solvent was evaporated‚ leaving
