the steps and procedures laid out for me. Results Experiment Results Predict Question: Predict Question 1: The molecular weight of urea is 60.07. Do you think urea will diffuse through the 20 MWCO membrane? Your answer : a. Yes‚ but very slowly. Predict Question 2: Recall that glucose is a monosaccharide‚ albumin is a protein with 607 amino acids‚ and the average molecular weight of a single amino acid is 135 g/mole. Which of the following will be able to diffuse through the 200 MWCO membrane

Farmers Market Lab Organic farming is a form of agriculture that relies on techniques such as crop rotation‚ green manure‚ compost‚ and biological pest control. Cunningham Organic Farming uses no pesticides and they use compost for fertilizers‚ "We use chicken manure called EZ Green Natural Organic Fertilizer" (Cunningham). Organic farming practices is helpful to our environment and what foods people consume‚ "We practice organic farming because we do

Restriction Fragment Length Polymorphism (RFLP) Restriction Fragment Length Polymorphism (RFLP) Definition Definition In molecular biology‚ restriction fragment length polymorphism‚ or RFLP is a technique that exploits variations in homologous DNA sequences. It refers to a difference between samples of homologous DNA molecules that come from differing locations of restriction enzyme sites‚ and to a related laboratory technique by which these segments can be illustrated. In RFLP analysis

Cardona‚ Jose Prof. Yun English 1A 23 July 2012 Conventional Farming V.S. Organic Farming Organic farming had not played a role in the market in the previous years‚ yet today it is common in grocery stores around the country. Organic farming refers to the way farmers grow and process agricultural products‚ such as fruits‚ vegetables‚ grains‚ dairy products and meat. Organic farming is also constantly referred to as healthy‚ smart‚ beneficial‚ and ecofriendly but these are words used in advertisement

Beta-Mercaptoethanol separated the Hemoglobin subunits they ended up at 16‚000 Daltons marker and not at 64‚000 Daltons which is Hemoglobin’s molecular weight. Another band can be seen at 32‚000 Daltons marker‚ which was a dimer of Hemoglobin that didn’t separate. Another band can be seen around the 64‚000 Daltons marker‚ which is where BSA ended up. BSA has a molecular weight of 66‚000 Daltons‚ which makes sense on where the band was observed. Sources of error may have been due to human error in performing

reactions in our body. Proteins are also capable of serving as antibodies to help protect our bodies from being invaded by outside substances or organisms. They are also an important part of the nervous system because proteins receive and respond to molecular signals that come from inside or outside the organism. Proteins also serve as a boat that transports substances within the organism and they can also regulate how a gen will be interpreted. The protein serves these functions and many

Identification of Mystery Plasmids Abstract Plasmids serve as important tools in genetics and biotechnology labs‚ where they are commonly used make many copies of a particular gene. The aim of this experiment was to identify three mystery plasmids based upon their characteristics; such as size‚ antibiotic resistance‚ lacZ profile and conjugative properties. The results obtained showed that plasmid number2 was the pDSK519 plasmid and its size was 26229.58 Bp. Plasmid pDSK519 also was found to be
