How many base pairs long is a typical gene? - ANS ~10^4bp. What is supercoiling? What is its purpose? - ANS The twisting of a DS DNA helix around itself allowing it to be packaged efficiently into a cell. Why might two sections of DNA which are the same length travel at different rates during gel electrophoresis? - ANS Some of the DNA, but not all, becomes relaxed during laboratory preparation (the state of a circular, non-supercoiled plasmid). Some of the DNA remains supercoiled and so is ...

The process mean and sample mean are the same. - ANS FALSE Two samples from the same population and taken at the same point in time are likely to have the same sample mean. - ANS FALSE A line chart is constructed from a scatter plot. - ANS TRUE A control chart must have an UCL and LCL but it is not necessary to have a centerline or target. - ANS FALSE Both an LCL and UCL must be included in every control chart. There are no exceptions. - ANS FALSE A stable process is one where all causes ...

Variation in production systems that is caused by factors that can be clearly identified and possibly even managed is called assignable variation. - ANS True An example of assignable variation in a production system may be that workers are not identically trained - ANS True An example of assignable variation in a production system may be that a machine is not adjusted properly - ANS True Variation that is inherent in a production process itself is called assignable variation. - ANS False ...
