Depurination HN 3. Hydrolysis of the N-glycosyl bond between deoxyribose and a purine base in DNA creates an apurinic (AP) site. An AP site creates a thermodynamic destabilization greater than that of any DNA base pair mismatch. HN 'N -O-P-O-CH2O Guanosine residue (in DNA) HH V a) Draw a G-C base pair. H b) See the figure to the right and speculate on some reasons why losing the purine base might be...

3. Answer the following questions that are based on the information in the abstract shown below. Jin H, Zhou H, Liu H, Chan W, Adhikary L, Mahmood K, Lee MS, Kemble G. (2005)Two residues in the hemagglutinin of A/Fujian 411/02-like influenza viruses are responsible for antigenic drift from A/Panama/2007/99. Virology 336(1):113-9. The H3N2 vaccine strain (A/Panama/2007/99) for the 2003-2004 influenza season did not antigenically match the circulating A/Fujian/411/02-like H3N2 viruses and had reduced effectiveness...

Can someone answer these questions please!? Need help!!!! 1. Compare the optimum pH results obtained for amylase and pepsin with those predicted in the Pre-Laboratory Assignment. Discuss any possible discrepancies between the predicted and experimental results. 2. What was the purpose of including control samples containing only substrate and buffer (test tubes 1−4 for each enzyme) in this study? Did any of these mixtures show any reaction? 3. Protein digestion involves the hydrolysis of peptide linkages and ...

INTRODUCTION In this section, you will introduce the experiment by explaining generally what you did and why you did it. This section usually starts with an examination of the literature through a library search to inform the reader about work already done on this topic. If you have never done a bibliographic database search for scientific journal articles, then you are not yet a biological sciences major (note:...
