Typically DamID results are normalized by using a ratio of the signal produced by the Dam methylase fused to the target protein (in this case lamin B1) divided by the signal produced by free Dam methylase. The results from lamin B1 DamID suggested that the genome could be divided into two main types of domains: Lamin Associated Domains (LADs) and the regions between these LADs (inter-LADs). In theory you would think that the same division could also be seen by ChIP-Seq using...

The screening was repeated using the 130mg of blood glucose per 100ml cut-off point in a population with an 8% prevalence of diabetes, as contrasted to the 5% prevalence in question 2, above. Calculate the sensitivity, specificity, PPV, and NPV. How do the sensitivity and specificity compare to what they were in the 5% diabetic population in question 2? How does the increased prevalence of diabetes affect the PPV? "Gold-Standard" Test Screening Disease No Disease Total Positive 263 64 327...

Q#3(Chapter 7). You learned that stocks could also be valued using the P/E ratio multiple method. (a) What are the main drawbacks of P/E multiple approach compared to constant dividend/cash flow models in valuing stocks? (b) If a firm's future earnings growth rate falls and its required return on equity (rs) rises due to Coronovirus effects, then what will happen to the firm's P/E ratio?
