DNA Aim This practical procedure allows you to amplify a 460 basepair fragment of DNA from within the control region of the mitochondrial genome. This can be done using three water baths or‚ if one is available‚ a thermal cycler (PCR machine). After it has been amplified‚ the DNA is run on an electrophoresis gel.

Osmolarity TITTLE: practical of estimation of osmolarity in tissues by bathing samples in hypertonic and hypotonic solutions. INTRODUCTION: Osmolarity is the osmolar concentration of plasma and is proportional to the number of particles per liter of solutions shown as (mmol/l). It is derived from the measures Na+ and K+‚ urea and glucose concentrations. Since the volume of solution changes with the amount of solute added also it change in temperature and pressure‚ osmolarity we can say it’s

Week Three Practical Problem Questions A. Determine T(n) for n = 6‚ 7‚ & 8. T(6)=(2*6*10*14)/(6-1)!=14 T(7)= (2*6*10*14*18)/(7-1)!=42 T(8)= (2*6*10*14*18*22)/(8-1)!=132 B. Do you detect a pattern to these numbers? This pattern may arise out of the numbers or the manner in which you generated triangulations. (A closed-form function for T(n) is relatively straightforward‚ but is fairly nontrivial to construct; you will not have to explore that here.) The pattern for these numbers
