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.

1. Presence of oncogenes (iaaM, iaaH and ipt) in T-DNA,

2. Their large size makes the handling procedures during cloning tedious and cumbersome

3. A general lack of unique cloning sites within the T-DNA, which are needed for the insertion of DNA segments to be cloned.

These three problems have been resolved by deleting
