Results(Analysis Questions): Dyes: #4‚ #6‚ and #10 traveled the fastest because they contained a protein with a molecular weight that was smaller than the others. The dye mixtures contained a sample of DNA‚ RNA or other protein. These were negatively charged so that they traveled toward the cathode. There were twelve samples in all‚ labeled #1-#12. Agarose

cytoplasm expand and flow around a relatively large or solid material and engulf it. 5. Circle the correct term. In active / passive processes‚ the cell provides energy in the form of ATP to power the transport process. Exercise Overview The molecular composition of the plasma membrane allows it to be selective about what passes through it. It allows nutrients and appropriate amounts of ions to enter the cell and keeps out undesirable substances. For that reason‚ we say the plasma membrane is

INTRODUCTION A major obstacle in the successful treatment of cancer is the development of resistance mechanisms to drug treatment. Various cellular changes that have been implicated in the development of drug resistance in cancer cells include: the increased expressions of P-glycoprotein (a multidrug transport protein) and multidrug resistance-associated protein (MRP-1); increased levels of the cellular detoxification protein‚ glutathione; and changes in the expression of apoptosis associated

RANELLE JANINE L. ASI BIO 120 S-5L EXERCISE 9. Genomic DNA Isolation & Exercise 10. Polymerase Chain Reaction (PCR) Cell and molecular biology is a science based on the various systems of a cell resulting to its regulation‚ maintenance and function. Many of these systems involve genetic information hence the study of the DNA is an essential part of this field. To able to analyze DNA‚ it must first be isolated and purified from its natural environment filled with biological molecules and compounds

How well did the results compare with your prediction? Urea molecules are too large (molecular weight of Urea is 60.07 g/mol) to pass through the 20 MWCO membrane. The results of the experiment correlated with my prediction. 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? As expected‚ glucose‚ with a molecular weight of approximately 180 g/mol‚ readily diffused across the 200 MWCO membrane;
