Let us assume that you are to characterize the mechanical interaction between cells cultured under 10 psig hydrostatic pressure and compare it with the mechanical interaction between cells cultured under normal atmospheric pressure. (a) What will you measure? In 10 words (maximum). With units. (b) List the main equipment that you will want to use. (c) Justify separately why each of the listed equipment will be needed. (d) Through a flowchart, explain how you will design the experiment in order to meet the objective above. (e) Pick any 3 equipment listed above and describe their (i) Basic principle, (ii) Design, (iii) Output, (iv) Any sample calculation that you may want to show. 

Suppose a father of blood type-b and a mother of blood type-O have a child of type-O. What are the chances that their next child will be blood type-O ?

Analyse the use of genetic technologies in relation to industry and/or medicine. The analysis will take into account the reasons and science behind the technologies, benefits to the relevant sector of industry or medicine, and include an appreciation  of efficacy and cost. This may be achieved effectively through the detailed examination of one  real-life example for each technology.

Show your complete solution to earn points. Glucose, a major energy-yielding nutri￾ent, is present in bacterial cells at a concentration of about 1.6mM (mM=millimolar). 

What is the concentration of glucose, expressed as mg/mL? How many glucose mol￾ecules contained in a typical E. coli cell? (Recall Avogadro’s number= 6.023x1023)

Given: Glucose concentration= 1mM= 1x10-3 mol/L, Molecular weight=180g/mol, Vol￾ume= 1x10-15 L

yeast cells can catabolise glucose under both aerobic conditions (respiration) and anaerobic conditions (fermentation/glycolysis). In this experiment, we will study both processes using a culture of Saccharomyces cerevisiae which has been aerobically adapted. By relating the amount of ethanol produced to the amount of glucose consumed over the same period of time, we will attempt to determine which process is the most efficient provider of energy to the yeast cells. This assumes of course that the energy needs of the cells are similar under the two sets of conditions. 

how can we determine which process is more efficient by calculating Moles ethanol produced per mole glucose catabolized ??

the current uses of genetic engineering techniques (i.e. extraction, PCR, electrophoresis) in medicine but also in industry. Try to give reasons why each technology is used (examples could include identification of disease, of faulty genes, identification of human remains, paternity and maternity tests).
