Precision will be reduced, but yield will be increased

Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.

Arrange in the order of their increasing capacity:

Which of the following are properties of steroid hormones?

I) Steroid hormones are lipid soluble and easily cross the phospholipid bilayer.

II) Steroid hormones usually exert their effects on target cells through membrane receptor proteins.

III) Steroid hormones act on cells close to where they were produced.

IV) Steroid hormones regulate gene transcription by binding to intracellular receptor proteins.
